CURRENT LIMIT
The MLP-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 MLP-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 MLP-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 MLP-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 MLP-Drive's Peak Current Limit (CP-81) can be set in the 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 “61” (Direct Enable)
Press “Enter”
Enter “1”
Press “Enter”
Use Motor Current (MP-82) to display the value, in amps, of the motor armature's current:
Press “Code Select”
Enter “82” (Motor Current)
Press “Enter”
The motor armature's present RMS current is displayed, in
amps.
