A2 – AMP-43140 (-D3140)
Description
The AMP-43140 resides inside the DMC-40x0 enclosure and contains four linear drives for operating small, brush-
type servo motors. The AMP-43140 requires a ± 12-30 VDC input. Output power is 20 W per amplifier or 60 W
total. The gain of each transconductance linear amplifier is 0.1 A/V at 1 A maximum current. The typical current
loop bandwidth is 4 kHz.
The AMP-43140 can be ordered to have a 100mA maximum current output where the gain of the amplifier is
10mA/V. Order as ‘-D3140(100mA)’.
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.
