Net FlowMeter
Lost, Chk Source
There is no drive on the Memobus Network with an analog Flow Meter.
Cause: With P1-01 = 3, P6-01 > 0 and P9-40 = 1 (Network), the Flow Meter function needs a valid Flow
Rate from the network originating from another drive that is also running the Flow Meter function
(P6-01 > 0) with P9-40 = 0 (Analog).
Countermeasure: If the drive has an operational Flow Meter connected to Terminal A1, set P9-40 = 0. If
another drive on the Memobus Network has a Flow meter connected to Terminal A1, confirm that drive is
online, with P6-01 > 0 and P9-40 = 0.
