No. Name Description Values
P9-30 Lag Drive Speed Follower Gain
Sets the gain to be applied to the speed of the current lead drive when P9-05 is set
to 3. The bias to be applied is set in P9-31.
Default: 100.0%
Min.: 0.0
Max.: 300.0
P9-31 Lag Drive Speed Follower Bias
Sets the bias to be applied to the speed of the current lead drive when P9-05 is set
to 3. The gain to be applied is set in P9-30.
Default: 0.00 Hz
Min.: -60.0
Max.: 60.0
P9-32
Lag Follower Deceleration
Time
Sets the deceleration time when the P9-33 timer is running and the drive is running
as Lag Drive Speed Follower (P9-05 is set to 3).
Default: 60.0 s
Min.: 0.0
Max.: 1000.0
P9-33
Lag Follower Deceleration
Time Active Time
Sets the time during which the deceleration time set in P9-32 is effective. The drive
will use the standard deceleration rate when it expires.
Setting this parameter to 0.0 disables the function.
Default: 0.0 s
Min.: 0.0
Max.: 360.0

current output speed.
Drive 3 is no longer needed and gets de-
staged.
Drive 2 is the Lead again.
Drive 1 follows the speed of Drive 2 again.
