Questions & Answers

The below represents frequent questions our support, engineering and sales teams have been asked over the years. If you have a question, please submit our contact us form to reach our application engineering team.

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 setup indexing via digital inputs? >

See the page Indexing

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.

The amplifier shows warning n17 after replacement of a S300 or S700. The old drive did not show any problem with CAN or EtherCAT. How can I reset the synchronized fieldbus operation? >

Set BUSP1 to 1 and finalize the configuration change with SAVE and COLDSTART.

Background: Bit 30 (COB-ID Setting for Tx-PDO) is supervised since Firmware 2.51. The amplifier sets the bit and expects the COB identifier is written with set bit 30, too (means: no RTR request of TX-PDOs is possible). 

If bit 0 is set to 1, then bit 30 is not supervised any more.

What is the resolution of the current controller? >

The incremental current actual value (iq, q component) of the current controller is triggered two times within 62,5µs and the values are added but the average is not determined. 

Units: ±3280 = ±DIPEAK in IncrAmpere?. 
DIPEAK = device peak current

Which test pulse is allowed at STO enable input? >

Pulse length < 100µs, off-time > 200ms. See page Test Pulse.

Do setup software and upgrade tool work with Windows Vista and Windows 7 ? >

Yes. The current tools work with Windows Vista and Windows 7 without restrictions.

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.

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.

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.

How can I protect the parameter set against write access? >

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

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.

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)
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).

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.

Positioning errors with AKM1 motors >

Low rotor inertia is the source for this problem, ironless linear motors show a similar behavior.

Solution for drives with S300/S700 servo amplifiers: 

How can an external zero sensor for homing be determined? >

Refer to page External zero pulse

Is it possible to switch over parameters during operation? >

Yes, either sequential with the function InxMODE=30 or with parallel switch over of two predefined parameter sets. Refer to page Switching over parameter sets.

What is a Bode Plot used for? >

Bode Plot is a process to analyze frequency behavior of the drive. See pages Tuning - Built in Frequency Analysis and Bode Diagram

Is it possible to operate DC motors? >

Yes, that's possible with S300 and S700. See page Operating DC motors S300-S700.
