RMS Technologies R356-RO CONTROLLER/DRIVER - Manual (Page 17)

o Move the motor (/1P800R moves the motor 2 revs if half stepping)
HyperTerminal Responses:
/0@ indicates good command and that it was received correctly
/0b indicates bad command
/0C indicates that the command is out of range
/0' indicates that the command is terminated
/0’a Overflow
Setting the Current
CAUTION! DO NOT SET THE CURRENT ABOVE THE MOTOR’S RATED
CURRENT.
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 3.0 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% = 0.21 0.30
20% = 0.43 0.60
30% = 0.64 0.90
40% = 0.86 1.20
50% = 1.07 1.50
60% = 1.29 1.80
70% = 1.50 2.10
80% = 1.71 2.40
90% = 1.93 2.70
100% = 2.14 3.00
Table 5: 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 5 we would see that 1.2 Amps is 40% of the driver’s maximum output current.
Assuming the R356 is addressed to Number 1, this is what you’d program: / 1m40R
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:
/1m46R
