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

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.

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}

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).

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

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.

7 axes additional to the master axis.

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.

Presumption is FW >7.22.
