C00018 | Switching frequency
Data type: UNSIGNED_8
Index: 24557
d
= 5FED
h
Selection of the pulse width modulated switching frequency transferred from the inverter to the motor
• When a variable switching frequency is selected, the switching frequency may change as a function of the load
and rotational frequency.

d
= 5FEC
h
Setpoint speed threshold for the automatic DC injection brake
• For speed setpoints with values below the thresholds a DC current is injected or the motor is not supplied with
current, depending on the setting.

C00021 | Slip comp.
Data type: INTEGER_16
Index: 24554
d
= 5FEA
h
Slip compensation for VFCplus and SLVC operating modes
• An increase of the slip compensation causes a greater frequency and voltage increase when the machine is load-
ed.
• After the motor to be used has been selected from the motor catalogue, the suitable value can be entered auto-
matically. An automatic detection via the motor parameter identification is possible as well.
