Precautions for setting:
★
F0-04 defines start/stop of inverter in preset speed operation mode.
★
External terminals set the acceleration/deceleration time in preset speed operation
mode.
★
Terminals F/R and RUN determines the running direction of motor in preset speed
operation mode.

Acceleration time is the time taken for output frequency to rise from 0Hz up to the
maximum frequency Fmax set by F0-16. Deceleration time is the time taken for
output frequency to drop from Fmax down to 0Hz. Both of them are not related to
forward/reverse.
EM303A provides 4 kinds of acceleration times and 4 kinds of deceleration times.
Each of them is set by independent parameter. There are 2 multi-function input
terminals which can be set as acceleration/deceleration time terminal 1 and 2. They
are programmable when inverter is running, and acceleration/deceleration time can be
changed immediately. See Table 7-5 for the programming mode of
acceleration/deceleration time terminal 1 and 2.
