Residual-current device.
The drive features 2 programmable relay outputs.
Save parameter settings in 4 set-ups. Change between the 4 parameter set-
ups and edit 1 set-up, while another set-up is active.
The drive compensates for the compressor slip by giving the frequency a
supplement that follows the measured compressor load keeping the com-
pressor speed almost constant.
A stop command belonging to Group 1 control commands, see the table
Function Groups under Control Command.

A temperature-dependent resistor placed on the drive or the compressor.
A state entered in fault situations, for example, if the drive is subject to an
overtemperature or when the drive is protecting the compressor, process,
or mechanism. The drive prevents a restart until the cause of the fault has
disappeared. To cancel the trip state, restart the drive. Do not use the trip
state for personal safety.
The drive enters this state in fault situations to protect itself. The drive re-
quires physical intervention, for example when there is a short circuit on
the output. A trip lock can only be canceled by disconnecting mains, re-
moving the cause of the fault, and reconnecting the drive. Restart is preven-
ted until the trip state is canceled by activating reset or, sometimes, by be-
ing programmed to reset automatically. Do not use the trip lock state for
personal safety.
Instant motor voltage.
Rated motor voltage (nameplate data).
Variable torque characteristics used for pumps and fans.
