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 1607
PARAM SAVE by setting the value to (1) SAVE…; 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 Terminal
designations 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.

+ +24 V DC or 24 V AC ± 10%
- 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.
