SDM-440x0 (-D4040,-D4020)
Description
The SDM-44040 resides inside the DMC-40x0 enclosure and contains four drives for operating two-phase bipolar
step motors. The SDM-44040 requires a single 12-30 VDC input. The unit is user-configurable for 1.4 A, 1.0 A, 0.75
A, or 0.5 A per phase and for full-step, half-step, 1/4 step or 1/16 step. A two-axis version, the SDM-44020 is also
available.
WARNING
Do not “hot swap” the motor power or supply voltage power input connections. If the amplifier is
enabled when the motor connector is connected or disconnected, damage to the amplifier can
occur. Galil recommends powering the controller and amplifier down before changing the connector,
and breaking the AC side of the power supply connection in order to power down the amplifier.
