Knowledge Base

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

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.

See the page Calculation of brake power

To change direction you must exchange sine and cosine.

Terminal: M SEARCHKOM 1

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

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.

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.

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

Presumption is FW >7.22. 

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

Select function 30 for a digital input:

INHCMD VSCALE –x
INLCMD VSCALE x

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.

7 axes additional to the master axis.

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.

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

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

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).

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

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

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)

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.

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}

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.

See the page Residual Current Protective Device.

See the page GrayCode

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.

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.

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.

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

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)

Depends on the feedback type. See page MultiFeedback
