Chapter 6. Function Description (FUN)
D
rpm: Speed difference
MaxSpeed
: Maximum speed ( FUN_04 )
AccTime
: Set acceleration time (FUN_40, 42, 44, 46)
St1_
D
rpm: Acc S Start ST (%) of FUN_36 at the time of acceleration,
Dec S End ST (%) of FUN_39 at the time of deceleration
St2_
D
rpm: Acc S End ST (%) of FUN_37 at the time of acceleration,
Dec S Start ST (%) of FUN_38 at the time of deceleration
St1_time: The time when St1_
D
rpm is formed.
St2_time: The time when St2_
D
rpm is formed.
4) FUN_48 (Deceleration time for zero speed selection)
5) FUN_49 (Zero speed deceleration time)
This is the time when the motor decelerates from the arbitrary speed to 0 rpm in speed. This is valid only when
FUN_48 is set to ‘Yes’. If ‘No’ is set, the set deceleration time is applied.

6) FUN_51(Decel time when emergency stop)
When the motor should be stopped immediately in case of emergency, BX on the control circuit terminal can be
used. When BX is ON, the motor decelerates to a stop within ‘Emergency deceleration time’ set at FUN_51. But, if the
motor does not stop within the deceleration time, it rotates freely after the deceleration time. If the motor is
intended to stop at the instant BX is ON, FUN_51 is set to ‘0’.

7) FUN_52 (Pre-excitation Time)
FUN_52 (Motor Pre-excitation Time) can be used for the flux build-up in the induction motor to obtain the best control
characteristic.
l
FUN_52 is activated only when FUN_02(Spd Ref Sel) is set to Keypad1 or Keypad2.
