A4 – AMP-435x0 (-D3540,-D3520)
Description
The AMP-43540 resides inside the DMC-40x0 enclosure and contains four sinusoidally commutated, PWM
amplifiers for driving brushed or brushless servo motors. Each amplifier drives motors operating at up to 8 Amps
continuous, 15 Amps peak, 20–80 VDC. The gain settings of the amplifier are user-programmable at 0.4 Amp/Volt,
0.8 Amp/Volt and 1.6 Amp/Volt. The switching frequency is 33 kHz. The amplifier offers protection for over-voltage,
under-voltage, over-current, short-circuit and over-temperature. Two AMP-43540s can be used for 5- thru 8-axis
controllers. A shunt regulator option is available. A two-axis version, the AMP-43520 is also available. If higher
voltages are required, please contact Galil.
Note: Do not “hot swap” the motor power or supply voltage power input connections. If the amp 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. The ELO input may be used to cut power to the motors in
an Emergency Stop or Abort situation.
