Parameter Descriptions 2-73
7000-TD002A-EN-P – September 2007
Torque Control Mode [Trq Control Mode]
Linear Number: 90
Default Value: Speed Reg
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the different torque control modes in the drive. Depending on the parameter
selection, the drive determines different torque command values. This parameter is used in conjunction
with an external torque command Trq Cmd External (91). This parameter is used for determining drive’s
torque output or torque limits. Typically the external torque command is linked to a PLC output. The
parameter is defined as:
Internal
Value
Enum Text Description
0 Zero Torque The drive issues zero torque command.
1 Speed Reg The drive uses the speed regulator to determine the torque
command.
2 Ext Torq Cmd The drive uses the external torque command and bypasses the
speed regulator. This mode is also referred to as “Slave” or “Torque
follower” mode.
3 Spd Trq Pos The drive uses the speed regulator with an external motoring torque
limit.
4 Spd Trq Neg The drive uses the speed regulator with an external braking torque limit.
5 Spd Sum The torque command is sum of speed regulator and the external
torque command.
Torque Limit Motoring [Trq Lmt Motoring]
Linear Number: 84
Default Value: 1.05
Minimum Value: 0.00
Maximum Value: 4.00
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the maximum value of the torque command when motoring. A value of 1.00
corresponds to rated motor torque.
Torque Limit Braking [Trq Lmt Braking]
Linear Number: 85
Default Value: 0.50
Minimum Value: 0.00
Maximum Value: 4.00
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the maximum value of the torque command when braking or regenerating. A
value of 1.00 corresponds to rated motor torque.
