PI Regulation.
1
Uses PI to determine speed.
Turn Off
2
The iQpump Controller stops running when it switches to a lag drive after P9-07 time expires.
Follow Lead Spd
3 The iQpump Controller follows the speed of the active Lead drive. Use P9-30 gain and P9-31 bias setting
to adjust reference signal.
P9-07 Lag Fixed Speed Delay
Time delay before execution of P9-05 selection when the iQpump Controller changes from lead to lag.
Range
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:
0 - 1000 sec
P9-30 Lag Drive Speed Follower Gain
Range
When P9-05 = 3, the drive will follow the speed of the active lead drive
0.0 - 300.0 %
applying this gain and P9-31 bias to the reference signal.
P9-31 Lag Drive Speed Follower Bias
Range
When P9-05 = 3, the drive will follow the speed of the active lead drive
-60.00 - 60.00 Hz
applying this bias and P9-30 gain to the reference signal.
P9-99 Network Compatibility Selection
Determines the communication compatibility for the iQpump Memobus Network.
Setting
A-Version 30034
0 Use this mode if (ONE or MORE) iQpump Controllers on the network have software version monitor U1-
14=30034 and nameplate PRG: 0034.
B-Version 30035+ (factory default)
1 Use this mode if (NONE) of the iQpump Controllers on the network have software version monitor U1-
14=30034 and nameplate PRG: 0034.
