JVL Industri Elektronik A/S - User Manual - Integrated Stepper Motors MIS23x, 34x, 43x 15
2.1 Power Supply
2.1.8 Control Voltage (CVI) - only MIS34x motors
The control voltage should be in the range 12-28VDC and is used to supply the micro-
processor circuit, internal functions in general and the user output driver (O1-8).
To ensure that position and parameters are maintained after an emergency stop, the
control voltage should be maintained under a stop situation where the P+ (main power)
is disconnected.
Warning: Control voltage higher than 30VDC will damage the controller.
2.1.9 Power Supply Grounding
It is recommended that the housing is connected to ground or common 0 VDC. The
overall earthing of the system must be done at a central point close to the power supply.
2.1.10 Dimensioning power supply and fuse - only MIS34x motors
The power supply must be dimensioned according to the actual motor size.
The size of the pre-fuse also depends on the actual model of the MIS motor.
Use the following table to select the power supply and fuse ratings.
Please notice that the specified wattage values are worst case values at maximum torque.
See also the appendix which shows the standard power supplies that JVL offers.
2.1.11 General power supply description
The supply voltage at the main power (P+ terminals) can be chosen in the range 12VDC
to 80VDC (nominal). However the maximum performance is based on a 80V DC supply.
A lower voltage will decrease the speed/torque performance.
See also the torque curves in the appendix Section 13.4, page 280.
