FAQs

Can I use a parameter set for an amplifier with another current class?

Parameter sets of S300 and S700 amplifiers can be used independant from amplifier type and current class.

How can I basically setup the current control parameters dependent on the used motor?

MLGQ = 12 * L{mH} * DIPEAK {A} / 1000
KTN 0.6

Example:
S603 --> Dipeak 6A
L=3mH - Motor inductance
MLGQ = 12 * L * DIPEAK / 1000 = 0.216
KTN 0.6

Leave all other values unchanged.

How can I calculate the brake power?

How can I change the rotation direction of SinCos Encoders?

To change direction you must exchange sine and cosine.

For more information refer to Motion direction - Parameters

How can I force a wake & shake with a ENDAT/Hiperface/BISS Feedback?

Terminal: M SEARCHKOM 1

How can I protect the parameter set against write access?

Yes, you can activate a password protection. Refer to page Password Protection.

How can I set up camming?

The servo amplifiers use position registers to define cams. The status of the registers are sent as cams to one or two digital outputs by a predefined function. Refer to page Setup of Camming S300-S700 or Setup of Camming S400-S600. You can define up to 8 cams for a digital output with S300/S700.

How can I setup indexing via digital inputs?

See the page Indexing

How can I start communication to an axis module, if communication is not possible after boot?

Start Hiperterminal: 

with no response; 
„\“ type until the command is accepted, then switch over with 
„\ 0“ to the master; 
type SCANX and 
Prompt „-->“ wait; 

Now communication is possible.

How can I start communication to the amplifier, if it doesn't boot correctly?

To start the amplifier in monitor mode, press both keys in the front panel simultaneously while when switching the drive on (24V on).

How can K and S be deactivated?

Presumption is FW >7.22. 

DRVCFG2 = -2147483648 (= -2^31, set bit 31).

How can the direction for an analog set point be inverted without changing the wiring?

Select function 30 for a digital input:

INHCMD VSCALE –x
INLCMD VSCALE x

For more information refer to Motion direction - Parameters

How long is the reaction time for position latch and what happens while latching?

20µs with a jitter of 1µs.

The moment of the position latching is determined. With the next cycle of the position controller the (T=250µs) the latch position is calculated. High speed deviation in this cycle can lead to determination errors.

How many axes can be supplied by a master module?

7 axes additional to the master axis.

I can't find my EnDat Motor in the motor database. What can I do?

Limit Ipeak and make sure, that no damage can occur even if the motor runs off.

Example 1: The motor type is not listed at all:

  • Select FBTYPE = 4, SAVE, COLDSTART
  • Read MPHASE, set MNUMBER = 0, SAVE; HSAVE and COLDSTART.

After rebooting, check MPHASE. If MPHASE no longer matches the original value, the source value must be set. Now all the motor parameters have to be determined.

Example 2: The motor is listed as a motor with resolver:

  • Select FBTYPE = 4, SAVE, COLDSTART
  • Read MPHASE, set MNUMBER = 0, SAVE; HSAVE and COLDSTART.
  • FBTYPE = 0, SAVE, and COLDSTART. Then select the appropriate resolver motor and save with SAVE, then COLDSTART.
  • FBTYPE = 4, SAVE and COLDSTART.

After rebooting, check MPHASE. If MPHASE no longer matches the original value, the source value must be set.

I changed a parameter with the GUI and saved it to the EEPROM but after restarting the amplifier the old value was used.

Parameters may be changed via a fieldbus (during the initialization) or by a defined command sequence via the digital inputs (INxMODE 30).

I have a motor, that is not listed in the motor database and that has no name plate. How can I setup this motor?

If the motor has a Resolver feedback, the page Setup of unknown motors describes the process.

Is it possible to communicate with several servo amplifiers simultaneously via RS232 (Multidrive)?

Serial Communication via RS232 physically works with one amplifier only, but if you have connected several amplifiers via CAN bus to the "first" amplifier, you can communicate with all of them via RS232. This works either with the setup software (Multidrive must be selected) or with e terminal program (see page Multidrive Communication via RS232).

Is it possible to drive High Frequency Motors (Spindles) with the servo amplifiers?

Yes. With the help of pole number setting. Refer to page Tuning - High Frequency Spindles S300-S700.

Is it possible to use motors with a feedback system without commutation information as a primary feedback.

Yes. A Wake & Shake function determines the absolute position of the permanent Magnets in relationship to the stator windings. See page Wake and Shake.

The servo amplifier does not react to the incremental set point at the AquadB input. Why doesn't the electronic gearing work?

Possible reasons:

  • OPMODE <> 4
  • AquadB interface not switchwed to input
  • Servo amplifier disabled (Enable=0) 
  • Limit switch active (warning n10 or n11 in the LED display)

What are the application requirements in case of a high altitude site, e.g. above 1,000m A.M.S.L.?

1.) <1000m A.M.S.L., no restrictions
     1000-2500m A.M.S.L. with power derating 1,5% / 100m
2.) According to Paschen the isolating capability of air is reduced. That reduces the max. allowed mains voltage to 400V.

What are the maximum ramp times?

The maximum ramp time in a motion task can be calculated by: 

t{ms} = 140/32 x nsetp with PRBASE 16, 20 oder 
t{ms} = 140/32 x 16 x nsetp with PRBASE = 24.

Reduction while braking: tmax = 8000ms
Speed controller: t{ms} = 140 x 128 x n{rpm}

What causes the error message F14?

Fault in the power output stage. Can also be triggered by a wrong or faulty motor cable, if the screen of the motor cable is not connected or if the motor is feaulty. Refer to page Error Message F14.

What do I have to consider when using a residual current protective device (RCD) in a servo system?

What does four quadrant operation mean?

What does Gray Code mean?

See the page GrayCode

What does Hardware Revision mean on the nameplate of the servo amplifier?

The Hardware Revision defines the development status of the servo amplifier. The same number can be found on the cover page of the instructions manual. Refer to page Hardware Revision Number.

What does P01, E01 or -S- mean in the display?

P01: 1A power stage, mains supply voltage switched on, power stage disabled
E01: 1A power stage, mains supply voltage switched on, power stage enabled
-S-: STO Enable input is not connected or no 24V signal is applied

Refer to page LED Display Codes S300-S700.

What is the current supply at the SinCos encoder interface?

At connector X1 there are 5V/150 mA available. These values are nominal even at maximum load. If a higher current is required, we offer an external power supply (350 mA) with a 1m cable. See instructions manual.

What is the maximum value for motor temperature sensor (PTC)?

S300: 5.0 kOhm
S400: 2.0 kOhm
S600: 1.6 kOhm
S700: 5.0 kOhm

What is the message level for amplitude error (F04) with SinCos encoders?

The SinCos amplitude monitoring enables the F04 error with:

  • FW 070 : F04 at approx. 1900 U/min
  • >=FW 072 : F04 at approx. 4500 U/min (approx. 150Khz)

The monitoring can be switched over in both firmware versions with CPHASE 2.

No communication to the encoder 

Solution: connect the encoder, check the cable 

Wrong data in the encoder 

This error occurs with new encoders, that have never been initialized.

Solution: Initialize the data with the command HSAVE (terminal screen)

See pages Supervision of Sine Cosine EncodersSetup of an Endat or Hiperface or BISS encoder and LED Display

What is the permitted length of the feedback cable?

Depends on the feedback type. See page MultiFeedback

What is the permitted length of the motor cable?

  • <10m: noise emission acc. to IEC 61800-3 category C2
  • >10m: noise emission acc. to IEC 61800-3 category C3
  • >25m: with motor choke 3YL (see Accessories Manual)
  • max: 50m

See Instructions Manual for more information.

Which acceleration and deceleration ramps are used in motion task series?

This can be selected on the screen page "Motion Task Parameters". Refer to page Motion Task Series.

Which delay time can occur during Master / Slave operation?

Incremental signals (AquadB): processing time in the servo amplifier (FPGA) are in "ns" range. Slave reaction time ±62,5µs (current control task).

Which settings are required for operating an induction machine?

Why are large set point steps (e.g. 0 >> 7 V) with OPMODE = 5 not executed?

Input filter isn't set correctly. Increase filter time constant of the analog input.

Why does n32 flash in the display?

The firmware of the amplifier is a beta version (not released). Refer to page LED Display Codes.

Why does the Multidrive communication not work?

  • Multidrive is not selected in the setup software
  • Master axis does not have ADDR 8
  • Different CAN baud rates are set
