Table A4.24: Amplifier Current Loop Gain Settings
Setting Peak and Continuous Current (TL and TK)
To set TL and TK for a particular motor, find the continuous current and peak current ratings for that motor and
divide that number by the amplifier gain. For example, a particular motor has a continuous current rating of 2.0 A
and peak current rating of 5.0 A. With an AG setting of 1, the amplifier gain of the AMP-43540 is 0.8A/V
TL setting = (2.0A) / (0.8A/V) = 2.5V (TL n=2.5)
TK setting = (5.0A) / (0.8A/V) = 7.5V (TK n=6.25)
Brushed Motor Operation
The AMP-43540 can be setup to run brushed motors by setting the BR command to 1 for a particular axis. Wire the
motor power leads to phases A and C on the motor power connector. Do not set BA, BM or use the BX command
for any axis that is driving a brushed motor.
