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

Recommended motor-drive-connection combinations shown in BOLD

Rack mounting power supply

MSE562

The MSE562 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 or

MSE875 units are recommended to drive up to 4 motors.

MSE562 provides a 35 Vdc motor rail for high speed operation

using the MSE570 Evo 2 drive.

Alternatively, where a motor is to be used at ultra high speed, the

MSE562’s 70 Vdc rail can be utilised in conjunction with a PM546
