Other issues and solutions
Motor runs at low speed
when high speed requested
•
Has a RPM value been set in P-10 which changes the frequency
parameters to RPM and then a low RPM value been set in P-01 –
Maximum speed.
•
The drive is in current limit which will hold the drives output frequency at
a low value. Check actual output current compared to 1.1 X P-08
(fan/pump) or 1.5 X P-08 (industrial). See

so the drive is
expecting a signal transition between 0V and 24V to allow it to run. If a
hardwire connection is between control terminals 1 & 2, the drive will
not run.

Not enough starting torque
for application
•
See Knowledge Base document
MCW-E3-044
•
Carry out an autotune (See parameter P-52)
•
Increase P-11 – Torque boost voltage in small increments.
The drive does not react to
signals on the analogue or
digital inputs
•
See Knowledge Base document
MCW-E3-037
•
Analogue inputs – Check P00.01 (AI 1 – terminal 6) and P00.02 (AI 2 –
Terminal 4). These should go from 0 to 100% = 0 to 10V/4-20mA etc.
•
Digital inputs – Check P00.04 (Digits should change from 0 to 1 when
digital inputs are connected to 24V.

applications
•
Set P-10 (motor rated speed) to 0 RPM.
•
If it is required to see RPM on the display, set P-10 to the synchronous
speed of the motor (3000, 1500, 1000, 750 RPM)
Display indications
Display shows STOP to indicate that no enable/run signal has been applied to the drive.
Display shows output frequency in Hz
Display shows output current in Amps
Display shows output power in kW
