NOTES
During PM sensorless vector control, the brake sequence function is available with the IPM motor
MM-CF only.
During deceleration, inverter output is shut OFF when the frequency reaches Pr. 13 "Starting fre-
quency" or 0.5 Hz, whichever is lower. For Pr. 278 "Brake opening frequency", set a frequency equal
to or higher than the Pr. 13 setting or 0.5 Hz.
Pr. 285 "Overspeed detection frequency" is valid under encoder feedback control (used with the
FR-A8AP (option)) even if a value other than "7 or 8" is set in Pr. 292 "Automatic acceleration/decel-
eration".
Setting Pr. 278 too high activates the stall prevention and may cause E.MB4.
E.MB4 occurs when the acceleration time from Pr. 13 to Pr. 278 + Pr. 280 reaches or exceeds 2 s.
