For the function of the electronic gear via the repetition frequency, the following set-
tings (examples) can be made at the frequency inverter of the Slave drive.

Select an operation mode for parameter
Operation Mode "3 – Frequency Speed Sensor 1", for the Master drive with speed
sensor feedback. In this operation mode, the speed of the Slave drive follows the
speed of the Master drive at the highest accuracy. Depending on the application,
you can also choose another operation mode for

modules with resolver interface EM-RES. The number of division marks is set
permanently to 1024.
The expansion module is equipped with a two-channel repetition frequency
output for push-pull operation (TTL).
Set the value for parameter
quency at the repetition frequency output. This is the number of pulses per motor
revolution for the repetition 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 maxi-

If not done yet after the commissioning, select one of the configurations with
electronic gear for parameter
controlled field-oriented control with electronic gear". Depending on the applica-
tion, another configuration with electronic gear can be selected, too.

For parameter
frequency and the type of evaluation, e.g. "62 – S6IND Double Evaluation pos.".
Since the rated speed decreases when the number of pole pairs is higher (n~1/p),
different speeds may result if the Master and Slave have the same reference fre-
quencies. Adjust the values for parameters
cy input of the Slave and
of the Master according to the number of pole pairs of the motors in order to ob-
tain the same speeds for the Master drive and the Slave drive. Different speeds
can be realized by setting the gear factor, as described in chapters "Setting a
Fixed Gear Factor" and "Setting a Variable Gear Factor".
