 Torque limit under speed control and position control
The following settings can be specified as a limitation set on the torque.
[1] TREF terminal voltage (10 V/300%)
[2] Forward rotation torque limit (PA1_27), reverse rotation torque limit (PA1_28)
[3] Second torque limit (PA2_58)
[4] Third torque limit (PA2_60)
If "0" is specified as torque limit selection (PA2_57), the settings of torque limit 0 and torque limit 1
are enabled.
Torque limit 1 Torque limit 0 Torque limit
OFF OFF Value of [2]
OFF ON [2] or [1], whichever is smaller
ON OFF [3] or [2], whichever is smaller
ON ON [3] or [1], whichever is smaller
If forced stop or servo-on is turned off, or if an over-travel or minor failure alarm is detected,
limitation is set at [4] third torque limit (PA2_62) the setting can be changed.
 Torque limit under torque control
The limit [2] is always enabled.
 Deviation hold selection at torque limit
Use deviation hold selection at torque limit (PA2_59) under position control to select the torque
limit for retaining the deviation amount.
Torque limit 1 Torque limit 0 Torque limit
OFF OFF [4] or [2], whichever is smaller
OFF ON [3], [2] or [1], whichever is the smallest
ON OFF [4], [3] or [2], whichever is the smallest
ON ON [4], [3] or [1], whichever is the smallest
Torque limit 1 Torque limit 0 Torque limit
OFF OFF No torque limit
OFF ON Value of [1]
ON OFF Value of [3]
ON ON PA2_59: 1, value of [3]. PA2_59: 2, value of [1]
