2.5 SPINDLE SYNCHRONOUS CONTROL
Optional function
2.5.1 Start-up Procedure
A. Check that operation in velocity control mode is ready.
B. Prepare and check the ladder programs for the spindle synchronous
control function.
C. Set the parameters related to spindle synchronous control.
D. Connect a position coder and check the feedback signal.
E. Check the spindle synchronous speed.
F. Check the direction of spindle rotation when spindle synchronous control
is applied.
- Direction of spindle motor rotation when spindle synchronous control is
applied.
G. Check that errors such as overshoot or hunting do not occur before the
spindle achieves the maximum speed for synchronization.
- Position gain for spindle synchronous control
- Acceleration/deceleration time constant used for spindle synchronous
control control
H. Check that the error pulse difference between the spindles is within ±5
pulses.
- Position gain for spindle synchronous control
- Spindle-to-motor gear ratio data
- Velocity loop proportional gain for spindle synchronous control
- Velocity loop integral gain for spindle synchronous control
- Incomplete integration coefficient
- Bell-shaped acceleration/deceleration time constant for spindle
synchronous control
- Motor voltage for spindle synchronous control
J. End the checking of spindle synchronous control operation.
I. Check the operation of spindle phase synchronization control.
- Shift amount for spindle phase synchronization
- Compensation data for spindle phase synchronization
