Acceleration And Deceleration Characteristics; Setting Acceleration And Deceleration Times - YASKAWA CIMR-ACA4011 Instruction Manual

Acceleration and Deceleration Characteristics

This section explains the acceleration and deceleration characteristics of the MxC.

Setting Acceleration and Deceleration Times

The "acceleration time" refers to the time it takes for the output frequency to climb from 0% to 100%, while
"deceleration time" refers the time taken for the output frequency drop down to 0%. The default acceleration
time is C1-01, and the default of the deceleration time is C1-02.

Description
Sets the time to accelerate from zero to maxi-
mum frequency.
Sets the time to decelerate from maximum
frequency to zero.
Sets the time to accelerate from zero to maxi-
mum frequency when selected via a multi-
function input.
Sets the time to decelerate from maximum
frequency to zero when selected via a multi-
function input.
Sets the time to accelerate from zero to maxi-
mum frequency when selected via a multi-
function input.
Sets the time to decelerate from maximum
frequency to zero when selected via a multi-
function input.
Sets the time to accelerate from zero to maxi-
mum frequency when selected via a multi-
function input.
Sets the time to decelerate from maximum
frequency to zero when selected via a multi-
function input.
Sets the setting resolution of C1-01 to C1-09.
0: 0.01 s (0.00 to 600.00 s)
1: 0.1 s (0.0 to 6000.0 s)
Sets the frequency for automatic switching of
accel/decel times.
Fout < C1-11: Accel/Decel Time 4
Fout≥C1-11: Accel/Decel Time 1
Multi-function inputs "Multi-Acc/Dec 1" and
"Multi-Acc/Dec 2" have priority over C1-11.
Note: With Multi-Function Input, Accel/
Decel Time 1 and 2 will take prece-
dence.
