(2) Notes on velocity loop high cycle management
(Torque command) Velocity loop high cycle management can be used
for tandem control in the following editions:
- Series 90B0/A(01) and subsequent editions
- Series 90B1/A(01) and subsequent editions
- Series 90B6/A(01) and subsequent editions
- Series 90B5/A(01) and subsequent editions
- Series 90D0/A(01) and subsequent editions
- Series 90E0/A(01) and subsequent editions
CAUTION
(Torque command)
When velocity loop high cycle management is used
in tandem control, the velocity feedback average
function must be enabled at all times. (See Subsec.
4.18.3.)
(3) Velocity loop integrator copy function
If the velocity loop integrator gets unbalanced between the master and
slave during synchronous or velocity command tandem control, the
axes may get twisted, leading to an OVC alarm.
This problem can be solved using a function that copies the velocity
loop integrator from the master axis to the slave axis, thereby
preventing integrator imbalance between the master and slave.

WSVCP
2273 (FS30i, 16i)
WSVCP(#1) 1: The loop integrator of the master axis is copied to the slave axis.
(Specify only the slave axis.)
(Series 9096, and Series 90B0/M(13) and earlier editions are not
supported.)
CAUTION
1 This function is applicable only to two axes
controlled on the same DSP.
2 No compatibility problem occurs between this
function and the system software.
3 This function bit is usable when simple
synchronous control or velocity command tandem
control is in use.
4 This function cannot be used together with the
preload or full-preload function.
5 It is impossible to specify functions related to the
velocity loop integrator (such as the incomplete
integral or low-speed integral function) separately
for the master axis and slave axis.
6 This function cannot be used together with servo
HRV4 control.
