Acceleration / Deceleration Times; Alternate Acceleration / Deceleration Times - Hitachi WJ200 Instruction Manual

ACCELERATION / DECELERATION TIMES

Changing the acceleration time to a shorter time can cause a E01, E02, or E03 over-current and or E05 over-load fault /trip, if this
occurs due to a short acceleration time increase the acceleration time and test again.
Changing the deceleration time to a shorter time can cause a E07 over-voltage fault/trip, if this occurs due to a short deceleration
time increase the deceleration time and test again.
Use the chart below to configure the standard acceleration and deceleration times.

ALTERNATE ACCELERATION / DECELERATION TIMES

The alternate acceleration and deceleration function can be used to switch from the standard acceleration and deceleration times to
an alternate acceleration and deceleration time based on a digital input, frequency break point, or reversal of direction command
(aka reverse plugging). If you plan to use switch by input [2CH] you will need to configure an available digital input function
for 09:[2CH] (example C006 = 09) and add the 24v circuit for that input.
Use the chart below to configure the standard acceleration and deceleration times.
