Parameters and firmware blocks
98
20.04 NEG SPEED ENA FW block: LIMITS (see above).
Selects the source of the negative speed reference enable command. See parameter 20.03 POS
SPEED ENA .
Bit pointer: Group, index and bit
20.05 MAXIMUM CURRENT FW block: LIMITS (see above).
Defines the allowed maximum motor current.
0…30000 A Maximum allowed motor current.
20.06 MAXIMUM TORQUE FW block: LIMITS (see above).
Defines the maximum torque limit for the drive (in percent of the motor nominal torque).
0…1600% Maximum torque limit.
20.07 MINIMUM TORQUE FW block: LIMITS (see above).
Defines the minimum torque limit for the drive (in percent of the motor nominal torque).
-1600…0% Minimum torque limit.
20.08 THERM CURR LIM FW block: None
Enables the thermal current limitation. Thermal current limit is calculated by the inverter thermal
protection function.
(0) ENABLE The calculated thermal current value limits the inverter output current
(i.e. motor current).
(1) DISABLE 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.
