RMS Technologies IMC17 INTEGRATED MOTOR CONTROLLER/DRIVER - Manual (Page 13)

In order to set the correct current for your motor, you must program the specified
amount in HyperTerminal
Current is set based on the Maximum amount of current the controller board can
output, which is 2.0 Amps Peak. Below is a table of how much current will be
applied to your motor for each setting.
Percent
Motor’s Current
Rating (Amps)
Driver’s Equivalent
Current (Amps)
10% = 0.14 0.20
20% = 0.28 0.40
30% = 0.42 0.60
40% = 0.57 0.80
50% = 0.70 1.00
60% = 0.85 1.20
70% = 0.99 1.40
80% = 1.13 1.60
90% = 1.27 1.80
100% = 1.41 2.00
Table 6: Desired Current
To achieve the equivalent Driver Current (Amps), multiply your motor’s
rated current by 1.4. Follow these examples:
Example One:
You have a motor that is rated at 0.85 Amps, 0.85 Amps x 1.4 = ~1.2 Amps. Using
Table 3 we would see that 1.2 Amps is 60% of the driver’s maximum output current.
Assuming the IMC17 is addressed to Number 1, this is what you’d program: / 1m60R
Example Two:
You have a motor that is rated at 1.0 Amps, and your Controller is addressed to
Number 1, this is what you’d program: /1m70R
This will set the controller to 1.4 Amps Peak. How did we get 1.4 Amps?  1.0
Amps x 1.4 = 1.4 A
WARNING!: Setting the Current to a value greater than the Motor’s rated
current will damage your motor, and may overheat the controller.
