77-MOL - Motor Overload Input
Sets Motor Overload Input Polarity.
81-PRGNO - Special Program Number L2
This parameter allows the storage, retrieval and exchange of customer defined program setups, as well as a
means of returning all parameters to factory defaults. Numerous special programs are also included at this
parameter. Standard data codes are outlined in the following table:
Data Code Description See Note
0 Standard Factory Program 1
1 Reset all parameters to factory settings 1, 2
2 Store customer parameter settings 1, 3
3 Recall customer parameter settings 1, 3
4 Exchange current with stored customer parameter settings 1, 3
5 Recalibration of a WFC2005-0x for use with a 3 HP motor from a single phase source 1, 4
10 Makes option parameters inaccessible 1
11 Makes option parameters accessible for viewing and change 1
30-31 EMOP and 5-speed operation (Crane & Hoist Industry, See Form 1041) 5
32-33 EMOP2 / EMOP3 Electronic Motorized Potentiometer speed control 5, 6
60-62 Program Sequencer (See the following discussion)
200-201 Reference Signal Reversing (See Form 1042) 5, 7
Parameter Units Level
72-ST1 - Auxiliary Output #1 (Open Collector) L2
73-ST2 - Auxiliary Output #2 (Open Collector) L2
74-ST3 - Auxiliary Output #3 (Open Collector) L2
75-STR - Auxiliary Relay Output L1
Each of these parameters work similarly with the open collector outputs at the terminal strip (designated
ST1, ST2 and ST3) and the auxiliary relay. The data code programmed at these parameters defines the
condition that activates that particular output (either open collector or relay). Each may be programmed as
follows to indicate:
Data Code Description
0 Output inactive.
1 No fault (becomes active when the inverter is ready).
2 Fault (refer to parameter 68-NRST for further information).
3 Motor running FWD or REV.
4 Motor running REV.
5 Motor running FWD.
6 Motor speed = 0 Hz.
7 Motor at speed.
8 Motor speed greater than value programmed at parameter 36-F5.
9 Drive operating in torque limit.
10 Drive operating near overtemperature limit.
11 Drive operating in LOCal Mode.
Data Code Description
0 Removal of high input (+24 VDC) from MOL causes an F07 Fault (N.C. operation)
1 High input on MOL will cause an F07 Fault (N.O. operation)
