CURRENT LIMIT
The ML-Drive provides current limiting for both RMS continuous duty and RMS peak
intermittent duty. The RMS current limit level is controlled by RMS Current Limit
(CP-80). The RMS peak current level is controlled by Peak Current Limit (CP-81). The
ML-Drive allows the RMS continuous duty load current to exceed the RMS Current Limit
(CP-80) level for an accumulated total of one minute out of ten minutes. If the load
current attempts to exceed the RMS Current Limit (CP-80) level for more than one
minute, then the ML-Drive will restrict the motor current to the RMS Current Limit (CP-
80) level for the remainder of the ten minute period. The RMS peak intermittent duty
load current is restricted to a level that is below the value that is entered in Peak
Current Limit (CP-81). See below for instructions on entering the RMS Current Limit
(CP-80) and the Peak Current Limit (CP-81).
The level of the ML-Drive's RMS Current Limit (CP-80) can be set in the range of
4.0 amps to 10.0 amps. Enter the value (in amps) at which you want to set the RMS
Current Limit (CP-80), as follows:
Press “Code Select”
Enter “80” (RMS Current Limit)
Press “Enter”
Enter the value at which you want to set the current limit
(range = 4.0 - 10.0 amps)
Press “Enter”
The level of the ML-Drive's Peak Current Limit (CP-81) can be set in a range of
4.0 amps to 15.0 amps. Enter the value (in amps) at which you want to set the Peak
Current Limit (CP-81), as follows:
Press “Code Select”
Enter “81” (Peak Current Level)
Press “Enter”
Enter the value at which you want to set the peak current limit
(range = 4.0 - 15.0 amps)
Press “Enter”
