Stepper motor drive current settings
MSE570
The motor phase current can be set to suit the motor to be driven by the use of the on-board DIP switch fitted to the
MSE570. The table below shows the nominal phase currents for each setting

Rack mounting power supply
MSE562
The MSE 562 is designed for mounting in a 3U high Eurorack and is
ideal for use with the MSE570 drive card. The unit will power up to 2
small motor axes or a single axis using a 34HS size motor. For
applications requiring multi-axis operation using a combination of
motors requiring high current settings the MSE173 Power supply is
recommended to drive up to 4 motors.
MSE562 provides a 35 Vdc motor rail for optimum high speed
operation using the MSE570 drive together with a 24 Vdc supply for
the drive’s on-board logic circuits.
Alternatively where a small motor is to be used with the PM546 Drive
to obtain ultra high speed operation the
70 Vdc rail may be utilised.
