Power Supply - Requirements and Precautions
For optimum performance and lifetime of the MIS motor, it is recommended that a ca-
pacitance of minimum 2200
μ
F is connected to the power supply that supply the P+ ter-
minal. It should be mounted as close as possible to the motor.
Also, it is recommended that minimum 0.75 mm² / AWG22 cable or 2 x 0.5 mm² is used
to connect the power supply to the motor. If the supply voltage drops below 7V, the in-
ternal reset circuitry will reset the driver and an under voltage error is generated. Provi-
sion should therefore be made to ensure that the supply voltage is always maintained at
a minimum of 7V, even in the event of a mains voltage drop.
CVI supply Precautions.
The CVI supply is not critical since the supply current is quite small (<200 mA). Only
make sure that the voltage stay at 24 VDC nominal and do not exceed 30 VDC.
A CVI voltage down to 7 VDC is also possible but a software setup is needed to allow
this. See also
Setup position backup using MacTalk
Warning:
A supply voltage at CVI or P+ higher than 100VDC will cause permanent
damages. A voltage over 30V at the CVI will activate a protection circuit
which shuts down the supply input. In this case CVI need to be disconnected
to reset the protection state.
Fuse dimensioning :
Dimensioning power supply and pre-fuse - MIS23x/MIL23x motors
Dimensioning power supply and pre-fuse - MIS34x/MIL34x motors
Earth
A capacitor in the power supply or
after the output is recommended.
Minimum 2200uF* and rated for 100V.
Prefered is a type with an low
ESR value.

This path must in total
be less than 10 meters
otherwise the peak

Do not place any components
in this path such as filter inductors,
diodes or resistors. Place any
components before the capacitor.
