Note:
• This function does not operate when the frequency reference is negative by using an analog input. To use rapid deceleration, the
frequency reference must be at least 0.
• Rapid deceleration is disabled when b1-04 = 1 [Reverse Disabled].
• The deceleration time set to C1-09 [Fast Stop Time] has priority in the following scenarios.
–Emergency stop operation has been executed by the detection of a fault
–The emergency stop command has been received from MFDI.
• The setting range of acceleration/deceleration time is determined by the setting of C1-10 [Accel/Decel Time Setting Units]. When C1-
10 = 0 (units of 0.01 seconds), the setting range of the acceleration/deceleration time is between 0.00 and 600.00 seconds.
