6.07 TORQ LIM STATUS FW block: DRIVE LOGIC (page 120)
Torque controller limitation status word.
Bit Name Val. Information
0 UNDERVOLTAGE 1 Intermediate circuit DC undervoltage *
1 OVERVOLTAGE 1 Intermediate circuit DC overvoltage *
2 MINIMUM TORQUE 1 Torque reference minimum limit is active. The limit is
defined by parameter 20.07 MINIMUM TORQUE. *
3 MAXIMUM TORQUE 1 Torque reference maximum limit is active. The limit is
defined by parameter 20.06 MAXIMUM TORQUE. *
4 INTERNAL CURRENT 1 An inverter current limit is active. The limit is identified by
bits 8…11.
5 LOAD ANGLE 1 For permanent magnet motor only: Load angle limit is
active, ie, the motor cannot produce more torque.
6 MOTOR PULLOUT 1 For asynchronous motor only: Motor pull-out limit is active,
ie, the motor cannot produce more torque.
7 Reserved
8 THERMAL 1 Bit 4 = 0: Input current is limited by main circuit thermal
limit. Bit 4 = 1: Output current is limited by main circuit
thermal limit.
9 I2MAX CURRENT 1 Inverter output current limit is active. **
10 USER CURRENT 1 Maximum inverter output current limit is active. The limit is
defined by parameter 20.05 MAXIMUM CURRENT. **
11…15 Reserved
* Only one of bits 0…3 can be on simultaneously. The bit typically indicates the limit that is
exceeded first.
** Only either 9 or 10 can be on simultaneously. The bit typically indicates the limit that is exceeded
first.
