46.09 STALL FUNCTION FW block: FAULT FUNCTIONS (see above)
Selects how the drive reacts to a motor stall condition. A stall condition is defined as follows:
• The drive is at stall current limit (46.10 STALL CURR LIM), and
• the output frequency is below the level set by parameter 46.11 STALL FREQ HI, and
• the conditions above have been valid longer than the time set by parameter 46.12 STALL TIME.
46.10 STALL CURR LIM FW block: FAULT FUNCTIONS (see above)
Stall current limit in percent of the nominal current of the motor. See parameter 46.09 STALL
FUNCTION.
0 …1600% Stall current limit.
46.11 STALL FREQ HI FW block: FAULT FUNCTIONS (see above)
Stall frequency limit. See parameter 46.09 STALL FUNCTION.
Note: Setting the limit below 10 Hz is not recommended.
0.5…1000 Hz Stall frequency limit.
46.12 STALL TIME FW block: FAULT FUNCTIONS (see above)
Stall time. See parameter 46.09 STALL FUNCTION.
0…3600 s Stall time.
46.13 FAN CTRL MODE FW block: None
Selects the fan control mode. Available in frame sizes A to D. See section Fan control logic.
(0) Normal Control mode based on the modulator ON/OFF status.
(1) Force OFF Fan is always OFF.
(2) Force ON Fan is always ON.
(3) Advanced Control mode based on measured temperatures of the power stage,
braking chopper and interface board.
46.14 FAULT STOP MODE FW block: None
Fault class selection for non-critical HW faults.
Use this parameter for configuring the following faults to the stop mode:
0003, 0005, 0007, 0008, 0011, 0012, 0015, 0024, 0025, 0029, 0030, 0036, 0038…0045, 0047…0051,
0053, 0054, 0057, 0059…0062, 0073, 0074, 0317.

1 = Enabled: Supervision enabled.
1 Ena warn (Enable warning)
0 = Disabled
1 = Enabled: Drive generates an alarm upon a stall condition.
2 Ena fault (Enable fault)
0 = Disabled
