SPEED
Bit pointer: Group, index and bit
20.05 MAXIMUM CURRENT
Defines the allowed maximum motor current.
0...30000 A
20.06 MAXIMUM TORQUE
Defines the maximum torque limit for the drive (in percent of the motor nominal torque).
0...1600%
20.07 MINIMUM TORQUE
Defines the minimum torque limit for the drive (in percent of the motor nominal torque).
-1600...0%
20.08 THERM CURR LIM
Enables the thermal current limitation. Thermal current limit is calculated by the inverter thermal
protection function.

Parameters and firmware blocks
FW block:
ENA.
FW block:
Maximum allowed motor current.
FW block:
Maximum torque limit.
FW block:
Minimum torque limit.
FW block: None
The calculated thermal current value limits the inverter output current
(i.e. motor current).
The calculated thermal limit is not used. If the inverter output current is
excessive, alarm IGBT OVERTEMP is generated and eventually the
drive trips on fault IGBT OVERTEMP.
