Pr.11 Deceleration Time; Pr.12 Acceleration Time - Danfoss 176F7300 Manual

This parameter is used to determine the time required for the AC drive to ramp from 0
Hz to its Maximum Output Frequency (Pr.03). The rate is linear unless S Curve is
"enabled". This rate of acceleration applies to any incremental increase in command
frequency unless selected using the Multi-Function Inputs, MI1 - 3. See Parameters 39,
40 and 41. Acceleration time 1 is the default when a Multi-Function Input Terminal has
not been programmed to select between Acceleration time 1 and Acceleration time 2.
Pr.11 Deceleration Time 1 (Can be programmed while the drive is running.)
Factory Setting d10.0 Sec
Units 0.1 Sec
Parameter value d0.1 - d600.0 Sec
This parameter is used to determine the time required for the AC drive to decelerate
from the Maximum Output Frequency (Pr.03) down to 0 Hz. The rate is linear unless S
Curve is "enabled". Deceleration time 1 is the default when a Multi-Function Input
Terminal has not been programmed to select between Deceleration time 1 and
Deceleration time 2.

Note: See Pr.101; Automatic Accel and Decel times are default. Change to "Linear
Acceleration/Deceleration" to enable manual adjustment.
Pr.12 Acceleration Time 2 (Can be programmed while the drive is running.)
Factory Setting d10.0 Sec
Units 0.1 Sec
Parameter value d0.1 - d600.0 Sec
This parameter determines the time required for the AC drive to ramp from 0 Hz to the
Maximum Operating Frequency (Pr.03). The rate is linear unless S Curve is "enabled".
The rate of acceleration applies to any incremental increase in command frequency
unless Acceleration Time 1 (Pr.10) is selected. Acceleration Time 1 and 2 may be
selected using the Multi-Function Inputs M1 - 3. (See Parameters 39, 40 and 41.)
