The current values in the above table show the maximum conditions at the thermal limit
of the EXP-24 controller. The Peak current is present only during acceleration to maximum
speed, under maximum load with a 20V dc input voltage; the Continuous current is only
present under continuous motion at maximum speed and maximum load. Actual input
current will vary depending on the actual load and duty cycle if the application but will not
exceed these values
Motor Power Wiring
Power is provided to the R, S, and T actuator phases using terminal blocks J6 – J8. The
J9 terminal block provides an internal connection to the controller case for PE ground
connection to the Motor. The terminal blocks are capable of accepting 24 AWG to 6 AWG
(0.2 – 16 mm
2
) conductors. A minimum of 12 AWG (2.5 mm
output power.
The controller is capable of providing three phase current of up to 30 A peak for one
minute and 25 A continuously. Conductor sizes and cable length must be designed for the
specific application. The maximum motor cable length is 20 feet (6 meters). For best ECM
practices use shielded cable with the shield connected in the cable gland.
