7 AUXILIARY AND APPLIED FUNCTIONS
(1) Control mode switching request device
Set the device to request switching of the control mode.
When the control mode switching request device is turned OFF to ON, the mode
is switched to the control mode set in the control mode setting device.
(2) Control mode setting device
Set the device to set the control mode after switching.
When the control mode switching request device is turned OFF to ON, the
following mode is applied based on the value set in the control mode setting
device.
Control mode setting device value
0
10
20
30
If the value of control mode setting device is outside the range at control mode
switching request, a minor error (error code: 155) will occur, and the control
mode is not switched.
(3) Speed limit value at speed-torque control
Set the speed limit value (absolute value) at speed control, torque control or
continuous operation to torque control. If the command speed exceeds the speed
limit value at speed-torque control, a minor error (error code: 315) will occur, and
the control is executed with the speed limit value at speed-torque control.
(4) Torque limit value at speed-torque control
Set the torque limit value (absolute value) in speed control, torque control or
continuous operation to torque control. If the command torque exceeds the
torque limit value at speed-torque control, a minor error (error code: 316) will
occur, and the control is executed with the torque limit value at speed-torque
control.
(5) Speed command device
Set the command speed at speed control and the speed limit command value to
servo amplifier at torque control or continuous operation to torque control.
The value of speed command device can be changed at any time.
POINTS
The actual motor speed may not reach the speed limit value depending on the
machine load situation during torque control or continuous operation to torque
control.
