6. After entering the frequency in p0113, parameter p0009 on the Control Unit must be set
to 0 "Ready" again.
7. The Control Unit re-initializes. After booting, the pulse frequencies recommended in
r0114[i] (i = 1, 2, ...) can be entered in parameter p1800 "Pulse frequency" of the DO
VECTOR.
Note
Entering the pulse frequency
The pulse frequency entered in p1800 must correspond precisely to the value given in
r0114[i]; otherwise, the entry will be rejected.

Maximum output frequency achieved by increasing the pulse frequency

The adjustable pulse frequencies - and therefore the output frequencies that can be
achieved with the factory-set current controller clock cycles - are listed below.

1.25 kHz:
- 3 AC 380 ... 480 V: ≥315 kW / 605 A
- 3 AC 500 ... 690 V: all power ratings
The maximum output frequency is limited to 300 Hz due to the closed-loop control.
