Mitsubishi FR-E520-0.1KN - Stall Prevention (Pr. 156)

PARAMETERS
127
CAUTION
The zero current detection level setting should not be too high, and the
zero current detection time setting should not be too long. Otherwise, the
detection signal may not be output when torque is not generated at a low
output current.
To prevent the machine and equipment from resulting in hazardous
conditions by use of the zero current detection signal, install a safety
backup such as an emergency brake.
4.2.32 Stall prevention (Pr. 156)
Pr. 156 "stall prevention operation
selection"
You can make setting to disable stall prevention caused by overcurrent, make setting
to disable the fast-response current limit (which limits the current to prevent the inverter
from resulting in an overcurrent trip if an excessive current occurs due to sudden load
variation or ON-OFF, etc. in the output side of the running inverter), and set the OL
signal output delay.
