0 No supervision
1 Low limit supervision
2 High limit supervision
Brake-on control

If the output frequency goes under/over the set limit (ID316) this function generates a
message via digital output depending
9
External brake ON/OFF control with programmable delay (parame-
ters ID352 and ID353)
External control mode (Menu M3; ID125)
The AC drive heatsink temperature goes beyond the set supervision
limits (parameters ID354 and ID355).
Rotation direction is different from the requested one.
External brake ON/OFF control (parameters ID352 and ID353); Out-
put active when brake control is OFF
The thermistor input of option board indicates motor overtempera-
ture. Fault or warning depending on parameter ID732.
Fieldbus digital input 1. See fieldbus manual.
Selects the analogue input to be monitored. See parameters ID356,
ID357, ID358 and ID463.
Fieldbus digital input 1. See fieldbus manual.
Fieldbus digital input 2. See fieldbus manual.
Fieldbus digital input 3. See fieldbus manual.
