YASKAWA TM.iQp.10 iQpump Technical Manual Supplement 45
P9-07 Lag Fixed Speed Delay
Time delay before execution of P9-05 selection when the iQpump Controller changes from lead to lag.
P9-30 Lag Drive Speed Follower Gain
P9-31 Lag Drive Speed Follower Bias
P9-99 Network Compatibility Selection
Determines the communication compatibility for the iQpump Memobus Network.
1
PI Regulation.
Uses PI to determine speed.
2
Turn Off
The iQpump Controller stops running when it switches to a lag drive after P9-07 time expires.
3
Follow Lead Spd
The iQpump Controller follows the speed of the active Lead drive. Use P9-30 gain and P9-31 bias setting
to adjust reference signal.
Range Description Default
0 - 1000 sec
When the drive changes from a lead to a lag and P9-05 ≠ 1, this time specified
in parameter P9-07 determines how long the speed is latched before executing
one of the following operations:
1. P9-05 = 0: Run at P9-06
2. P9-05 = 2: Turn off
3. P9-05 = 3: Follow the Lead Drive's speed.
5 sec
Range Description Default
0.0 - 300.0 %
When P9-05 = 3, the drive will follow the speed of the active lead drive
applying this gain and P9-31 bias to the reference signal.
100.0 %
Range Description Default
-60.00 - 60.00 Hz
When P9-05 = 3, the drive will follow the speed of the active lead drive
applying this bias and P9-30 gain to the reference signal.
0.00 Hz
