Acceleration switch point on spindle synchronous control
Unit of data 1min
-1
Valid data range : 0 to 32767
Standard setting : 0
The acceleration for spindle synchronous control changes according to
the speed set in this parameter as follows:
• Area where the spindle speed does not exceed the speed set in
this parameter
The acceleration for spindle synchronous control is constant (as
set in parameter No. 4032).
• Area where the spindle speed exceeds the speed set in this
parameter
The acceleration for spindle synchronous control decreases in
inverse proportion to the speed.
NOTE
1 Set the same data for the first spindle and second
spindle. If different data is set, synchronization
between the two spindles is not guaranteed.
2 When this parameter is set to 0, linear
acceleration/deceleration (constant acceleration) is
performed.

Bell-shaped acceleration/deceleration time constant for spindle synchronous
control
Unit of data : 1msec
Valid data range : 0 to 512
Standard setting : 0
This parameter sets a bell-shaped acceleration/deceleration time
constant for spindle synchronous control.
This parameter is applied to the move command after "Acceleration at
spindle synchronous control" (parameter No. 4032) is applied.
When this parameter is set, the spindle synchronous speed control
completion signal (FSPSY), output when the synchronous speed is
first reached after the spindle synchronous control mode is entered, is
delayed by the set time.
NOTE
Set the same data for the first spindle and second
spindle. If different data is set, synchronization
between the two spindles is not guaranteed.
