Adjustment of the output torque (current) of the motor
4
PARAMETERS
(6) To further prevent a trip (Pr. 154)
 When Pr. 154 is set to "0", the output voltage reduces during stall prevention operation. By making setting to reduce
the output voltage, an overcurrent trip can further become difficult to occur.
 Use this function where a torque decrease will not pose a problem.
(7) Limit the stall prevention operation and fast-response current limit operation according to
the operating status (Pr. 156)
 Refer to the following table and select whether fast-response current limit operation will be performed or not and
the operation to be performed at OL signal output.
*1 When "Operation not continued at signal output" is selected, the " " fault code (stopped by stall prevention) is displayed and operation
stopped.
*2 Since both fast-response current limit and stall prevention are not activated, OL signal and E.OLT are not output.
*3 The settings "100" and "101" allow operations to be performed in the driving and regeneration modes, respectively. The setting "101" disables the
fast-response current limit in the driving mode.

CAUTION
 When the load is heavy, the elevator is predetermined, or the acceleration/deceleration time is short, stall prevention is activated
and acceleration/deceleration may not be made according to the preset acceleration/deceleration time. Set Pr. 156 and stall
prevention operation level to the optimum values.
 In vertical lift applications, make setting so that the fast-response current limit is not activated. Torque may not be produced,
causing a drop due to gravity.
