Galil Motion Control (Rocklin, CA) has announced the AMP- 43240 4-axis servo drive that provides up to 750W per axis. It resides inside the DMC-4040 or DMC-4143 4-axis motion controller enclosure. The packaging of the multi-axis drives with the motion controller is designed to save space and wiring. The drive contains four transconductance PWM amplifiers for driving brushless servo motors at 20-80 VDC. Each amplifier drives motors operating up to 10A continuous, or 20A peak, per axis. The gain settings of the amplifier are user-programmable at 0.5, 1.0, and 2.0 Amp/Volt. The switching frequency is 24 kHz. The amplifier offers protection for over-voltage, under-voltage, over-current, short-circuit and over-temperature. A shunt regulator option is available.
The controller and drive package measures 8.1 × 7.3 × 1.7". Two 4-axis drives can also be installed inside the 8-axis controller package, which measures 11.5 × 7.3 × 1.7".
