A1 – AMP-430x0 (-D3040,-D3020)
Description
The AMP-43040 resides inside the DMC-40x0 enclosure and contains four transconductance, PWM amplifiers for
driving brushless or brush-type servo motors. Each amplifier drives motors operating at up to 7 Amps continuous,
10 Amps peak, 20–80 VDC. The gain settings of the amplifier are user-programmable at 0.4 Amp/Volt, 0.7
Amp/Volt and 1 Amp/Volt. The switching frequency is 60 kHz. The drive for each axis is software configurable to
operate in either a chopper or inverter mode. The chopper mode is intended for operating low inductance motors.
The amplifier offers protection for over-voltage, under-voltage, over-current, short-circuit and over-temperature.
Two AMP-43040s are required for 5- thru 8-axis controllers. A shunt regulator option is available. A two-axis
version, the AMP-43020 is also available. If higher voltages are required, please contact Galil.
