4.7.2 Gear factor
Via parameters
Gear Factor Numerator 1123 and Gear Factor Denominator 1124,
the gear factor is set permanently at the frequency inverter of the Slave drive.

4.7.3 Resynchronization
Limitation of acceleration when the gear factor is changed is effected via parameter
Resync. on Change of Gear-Factor 1142. The slave is resynchronized with the mas-
ter when the gear factor has changed. This function avoids sudden speed changes.
Resync. on Change of
Gear Factor 1142
Function
0 - Off Resynchronization is switched off.
1 - On
The slave is resynchronized with the master frequency
when the gear factor has changed.
The drive adjusts to the new frequency. The accelera-
tion ramps set in the motion block are considered.
If the gear factor changes, signals "57 – In Gear" and
"624 – In Gear" are reset. As soon as the new fre-
quency is reached, the signals are set again.
4.7.4 Phasing function
With the phasing function, the slave position is offset from the physical position of
the master by the value entered in
Phasing: Offset 1125.
The function can be executed via a logic signal assigned to parameter
Start Phasing
1128. After start,
Phasing: Speed 1126 and Phasing: Acceleration 1127 are used
until the slave position is offset from the master position by
Phasing: Offset 1125.
