PARAMETERS
<Setting of stall prevention operation level>
• In Pr. 22, set the stall prevention operation level. Normally set it to 150% (factory
setting). Set "0" in Pr. 22 to disable the stall prevention operation.
• To reduce the stall prevention operation level in the high-frequency range, set the
reduction starting frequency in Pr. 66 and the reduction ratio compensation factor in
Pr. 23.
Formula for stall prevention operation level
Stall prevention operation level (%) = A + B × [] × []
where, A = , B =
• By setting "9999" (factory setting) in Pr. 23, the stall prevention operation level is
constant at the Pr. 22 setting up to 400Hz.
