5 Spindle Axis Operation
5-4
Observe the following precautions for the operating speed of spindle axes in speed control.
• The SERVOPACK is in Position Control Mode when it is first turned ON. Execute the VELCTRL (3C hex)
command to change to Speed Control Mode.
• Due to the characteristics of the spindle motor, do not execute the SV_ON (31 hex) command immediately
after executing the SV_OFF (32 hex) command. This can subject the spindle motor to shock and vibration.
• Start the operating speed (e.g., M03 S2000) by executing the VELCTRL (3C hex) command after the
SV_ON (31 hex) command. To stop an axis (e.g., M05), set the speed reference in VREF to 0 with the
VELCTRL (3C hex) command to decelerate the spindle motor to a stop. After the spindle motor decelerates
to a stop, execute the SV_OFF (32 hex) command to turn the servo OFF.
• Torque limits are generally not used in Speed Control Mode. The torque limit setting (TLIM) is also not
effective for the VELCTRL (3C hex) command. Set parameters Pn430 (Torque Limit (Powering)) and
Pn431 (Torque Limit (Regeneration)) to limit the torque.
