(c) Acceleration/deceleration processing at continuous operation to torque
control mode
Acceleration/deceleration is a trapezoidal acceleration/deceleration
processing. Set acceleration/deceleration time toward "Speed limit value at
speed-torque control" in "Command speed acceleration time" and
"Command speed deceleration time". The value when the control mode
switching request device turns OFF to ON is valid.
Command speed during continuous operation to torque control mode is
limited with "Speed limit value at speed-torque control". If the speed exceeds
speed limit value is commanded, a minor error (error code: 315) will occur,
and the operation is controlled with speed limit value.
Confirm the command speed to servo amplifier with command speed
(#8004+20n, #8005+20n).

(d) Precautions at continuous operation to torque control mode
The following servo amplifier functions cannot be used during continuous
operation to torque mode.
• Base cut delay time function
• Forced stop deceleration function
• Vertical axis freefall prevention function
