CHAPTER 2 WIRING
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.
