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.
C1-10 Accel / Decel Time Setting Unit
If any of the parameters C1-01 to C1-09 are set to 600.1 seconds or more, C1-10 cannot be set to 0.
C1-11 Accel/Decel Switch Frequency
Setting Range: 0.0 to 200.0 Hz
Factory Default: 0.0 Hz
The Drive can be programmed to automatically switch between the two sets of Accel/Decel parameters on the fly. No digital
input is required. If parameter C1-11 is set to a frequency other than zero, the Drive will use Acceleration 1 and Deceleration 1
whenever the output frequency is equal to or above the value of C1-11 and use Acceleration 4 and Deceleration 4 whenever
the output frequency is below the value of C1-11.
A multi-function input programmed as “Multi-Acc/Dec 1” and “Multi-Accel/Dec 2” will have priority over C1-11. For example,
if the output frequency is greater than the value of C1-11 but a digital input configured as “Multi-Acc/Dec 1” is closed then Accel-
eration 2 and Deceleration2 are active.
