* If ITR is less than IFOT (IROT) in Vector Control Mode, or if IOUT is less than IFOT (IROT) in V/f Control mode, then the output frequency
during FCR will become TCR during run.
IOUT : Inverter Output Current
BDT : Brake Operation Delay Time
I T R : Inverter Torque Command
FCR : Impact Stop Clip Frequency (S3 -01)
FHF : FWD Brake Release Frequency (S1 -12)
TCR : Impact Stop Clip Time (S3 -02)
FHR : REV Brake Release Frequency (S1 -13)
IFOT : Forward Impact Stop Detection Torque (S3 -03)
based on motor rating
HF
: Slip Prevention Frequency (S1 -14)
IROT : Reverse Impact Stop Detection Torque (S3 -04)
based on motor rating
HT
: Slip Prevention Time (S1 -15)
TIOT : Impact Stop Detection Time (S3 -05)
(1) If the Impact Stop Command (setting = 35) is closed and the output frequency is at or above the Impact Stop Clip
Frequency (FCR), then the drive will decelerate to the Impact Stop Clip Frequency that has been set once a stop
command is input (both FWD and REV circuits are open).
(2) If the torque reference (or output current in V/f Mode) is at or above IFOT (or IROT in reverse) for longer than the
duration set to TIOT when running the drive at the Impact Stop Clip Frequency (FCR), then deceleration will occur
until the output frequency reference equals the value in FRF (or FRR in reverse). Next the Brake Release
Command (BR) will open, after which the brake Release Answer back (BX) relay will open from an external
circuit.
(3) If the conditions described above in (2) are not met for the duration set to TCR, then the Brake Release Command
(BR) will open after which the Brake Release Answer back (BX) will also open from external circuitry.
(4) If an Impact Stop occurs during run and the Impact Stop Command relay is opened, then the Impact Stop function
will cease and the Brake Release Command switch will open. Afterwards, the Brake Release Answer back (BX)
will also open via external circuitry.
