Setting The Acceleration/Deceleration Time - Omron SYSDRIVE 3G3MV User Manual

Basic Operation

5-7 Setting the Acceleration/Deceleration Time

The following description provides information on parameters related to
acceleration and deceleration time settings.
Trapezoidal and S-shape acceleration and deceleration are available.
Using the S-shape characteristic function for acceleration and decelera-
tion can reduce shock to the machinery when stopping or starting.
H Acceleration/Deceleration Time Unit (n018)
·The acceleration and deceleration time of the Inverter can be set within a range from
0.0 to 6,000 s without changing the default setting. If a more precise unit of setting is
required, this parameter can be set for 0.01-s increments. In this case, the setting
range will be from 0.00 to 600.0 s.

H Setting the Acceleration/Deceleration Time (n019 through
n022)
·Two acceleration times and two deceleration times can be set.
·The acceleration time is the time required to go from 0% to 100% of the maximum fre-
quency and the deceleration time is the time required to go from 100% to 0% of the
maximum frequency. The actual acceleration or deceleration time is obtained from the
following formula.
Acceleration/Deceleration time = (Acceleration/Deceleration time set value)
Acceleration time 2 and deceleration time 2 are enabled by setting 11 for acceleration/
deceleration time selection in any of the n050 through n056 parameters for multi-func-
tion input.
Deceleration time 2 is also enabled by emergency-stop settings 19, 20, 21, and 22 in
any of the parameters for parameters n050 through n056 for multi-function input with
n005 for interruption mode selection set to 0 (i.e., deceleration stop).
