Cascading factor (C0473/1 and C0533)
This function is valid only if the configuration is not changed.
The following constants for the master frequency input (X9) can be set under C0425:
l 16384 inc/rev.
l 8192 inc/rev.
l 4096 inc/rev.
l 2048 inc/rev.
l 1024 inc/rev.
l 512 inc/rev.
l 256 inc/rev.
Cascading factors which cannot be raised to the power of two can be assigned via C0473/1 and
C0533. The following connection applies:

The quotient is limited to a maximum of ±32767.
Setting range of factors:
l C0473/1: −32767 ... +32767
l C0533: +1 ... +32767
Setpoint conditioning of the slave
The value read by the input Dig.−Set (X9) is the setpoint (speed and phase) for the internal control.
Differences compared to the speed control:
l No setpoint integrator in the setpoint channel
l Change to the JOG value is not possible
l The additional setpoint is not active
l The CW/CCW changeover must be performed via the sign of the gearbox factor
QSP at the slave
If you set QSP at the slave drive, the setpoint (C0050) is decelerated along the QSP ramp. Home
positions get lost. A driftfree standstill is obtained since the set phase is led by the QSP integrator
when switching QSP.
CINH at the slave
If a slave drive is inhibited, the motor is coasting at the friction torque. The master frequency output,
however, continues to output the setpoint for the following slave. If the slave is enabled again, the
drive accelerates to its setpoint. (possibly at the current limit). When CINH is set, the phase
integrators are set to zero. Home positions get lost.
Exception:
If pulse inhibit (IMP) is released due to short−term mains undervoltage (< 500 ms), the phase
integrators are not reset. After mains recovery, the drive is able to follow its setpoint again. A phase
difference which emerged before is balanced.
