Changing Stall Prevention Level during Operation Using an Analog Input

If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) to 8 (stall prevention during
operation level), you can change the stall level during operation by setting H3-10 (Gain (Terminal A2)) and
H3-11 (Bias (Terminal A2)).
The stall prevention level during operation enabled is the multi-function analog input terminal A2 input level
or the set value in parameter L3-06, whichever is the smaller.

If the motor capacity is smaller than the Inverter capacity or the motor stalls when operating at the factory set-
tings, lower the stall prevention level during operation.

Detecting Motor Torque

If an excessive load is placed on the machinery (overtorque) or the load is suddenly lightened (undertorque),
an alarm signal can be set to multi-function output terminal M1-M2, M3-M4/P1-PC, or M5-M6/P2-PC.
To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection NO/
NC) in one of the following parameters: H2-01 to H2-03 (selects functions for multi-function output terminals
M1-M2, M3-M4/P1-PC, or M5-M6/P2-PC).
The overtorque/undertorque detection level is the current level (Inverter rated output current 100%) in V/f
control, and the motor torque (motor rated torque 100%) in vector control.
