AMP-43640 (-D3640)
Description
The AMP-43640 contains four linear drives for sinusoidally commutating brushless motors. The AMP-43640
requires a single 15–40VDC input. Output power delivered is typically 20 W per amplifier or 80 W total. The gain of
each transconductance linear amplifier is 0.2 A/V. When used with a 24VDC power supply, the amplifier will deliver
1A continuous and 2A peak. The current loop bandwidth is approximately 4 kHz. The amplifier will use 12 bit DACs.
There is an option for 16 bit DACs to increase the current resolution for systems with high feedback gain.
WARNING
Do not “hot swap” the motor power or supply voltage power input connections. If the amplifier 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.
