MPOW-01 auxiliary power extension module
Description
The MPOW-01 auxiliary power extension module is used in installations where the
drive's control part is required to be powered during network failures and
maintenance interruptions. The MPOW-01 provides auxiliary voltages to the control
panel, fieldbus and I/O.
Note:
If you change any of the drive parameters when the drive is powered
through the MPOW-01, you have to force parameter saving with parameter
by setting the value to (1)
; otherwise all changed data
will be lost
.
Electrical installation
Wiring
• Use 0.5…1.5 mm
2
(20…16 AWG) shielded cable.
• Connect the control wires according to the diagram in section
below. Use a tightening torque of 0.8 N·m (7 lbf·in).
Terminal designations
The diagram below shows the MPOW-01 terminals and how the MPOW-01 module is
connected to the external power supply and how the modules are daisy chained.

Terminal SCR is internally connected
to the analog ground (AGND) of the
drive.
All terminals are connected together
inside the module allowing daisy
chaining of the signals.
