Galil Motion Control DMC-40 0 Series

Electrical Specifications
The amplifier is a brush/brushless trans-conductance PWM amplifier. The amplifier operates in torque mode, and
will output a motor current proportional to the command signal input.
Supply Voltage: 20-80 V
DC
Continuous Current: 7 A
Peak Current 10 A
Nominal Amplifier Gain 0.7 A/V
Switching Frequency 60 kHz (up to 140 kHz available-contact Galil)

The default PWM output operation on the AMP-430x0(-D3040, -D3020) is Inverter Mode. The
minimum inductance calculations above are based on Inverter mode. If you have a motor with lower
inductance, Chopper mode can be applied for the PWM output. Contact a Galil Applications Engineer
to review minimum inductance requirements if Chopper mode operation is required.
