WARNING
The control functions listed in the following table may affect the synchronous operation
of the drives. It should be checked if these additional control functions are switched on
and if they are required.

Controller Status
The function of the electronic gear is realized by configuring digital inputs of the slave frequency in-
verter as a reference frequency input. If the master drive is a frequency inverter, the repetition fre-
quency output of the master frequency inverter is used.
7.5.4.6.1 Frequency inverter as master drive
If the master drive of the electronic gear is a frequency inverter, the following parameters (for exam-
ple) can be set for the transmission of the repetition frequency.
• Select operation mode "20 – Repetition Frequency MFO1F" for parameter
550. As a result, the multifunction output is used as a repetition frequency output.

at the repetition frequency output. This is the number of pulses per motor revolution for the repe-
tition frequency. The pulse duration depends on the motor speed. By default, this parameter is set
to 1024. When making the settings, take the frequency limit of the frequency output of 150 kHz
into account. The maximum value S

• Since the rated speed decreases when the number of pole pairs is higher (n~1/p), different
speeds may result if the master drive and slave drive have the same reference frequencies. Adjust
