C1 Accel/Decel
C1-01 Acceleration Time 1
C1-02 Deceleration Time 1
C1-03 Acceleration Time 2
C1-04 Deceleration Time 2
Setting Range:
0.0 to 6000.0 Seconds
Factory Default: 30.0 Seconds
C1-01 (Acceleration Time 1) sets the time to accelerate from zero to maximum speed (E1-04). C1-02 (Deceleration Time 1) sets
the time to decelerate from maximum speed to zero. C1-01 and C1-02 are the factory default active accel/decel “pair”. Another
accel/decel pair (C1-03 and C1-04) exists that can be activated by a multi-function digital input (H1-0x= 7), or
specified by a switch over frequency as programmed in parameter C1-11.
Note: In fan applications employing duct high pressure safety limit switches, it may be necessary to further adjust the
deceleration time to avoid high pressure limit trips due to damper closure as the system is shut down (an alternate solution in
this situation is to set parameter
b1-03
to “Coast to Stop”).
C1-09 Fast Stop Time
Setting Range:
0.0 to 6000.0 Seconds
Factory Default: 10.0 Seconds
A special deceleration parameter is available for use with emergency or fault operations. Parameter C1-09 will set a
special deceleration that can be operated by closing a digital input configured as H1-0x= 15 or H1-0x= 17. A digital input
configured as H1-0x= 15 will look for a switch closure before initiating the Fast Stop operation. A digital input configured as
H1-0x= 17 will look for the switch opening before initiating the Fast Stop operation.
Unlike a standard deceleration time, once the Fast Stop operation is initiated even momentarily, the Drive cannot be
re-operated until the deceleration is complete, the Fast Stop input is cleared, and the Run command is cycled.
