60 Parameters
2606
EFFECTIVE
SWITCHING
FREQUENCY
Sets maximum effective switching frequency of the
drive. If “rEd” is displayed, the switching frequency
has been reduced to the level in Parameter
0417
INTERNAL EFFECTIVE SWITCHING FREQUENCY
due to excessive drive heat sink temperature.
Refer to parameter

THERMAL
OVERLOAD VALUE
RETENTION 0 : DISABLED
0 : DISABLED
Alternative means of protecting the motor from
thermal overload must be applied (e.g. PTC
thermistor)
1 : ENABLED
The drive will retain the motor thermal overload value
following a mains power cycle.

32 SUPERVISION
Signal supervision. The drive monitors whether
certain user selectable variables are within the user-
defined limits. The user may set limits for speed,
current etc. Supervision status can be monitored with
relay output. See parameter group 14 RELAY
