Hitachi WJ200 - ACCELERATION; DECELERATION TIMES

Page 9
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.
Function
Parameters
Example Value
Acceleration Time F002 2.50 seconds
Deceleration Time F003 1.00 seconds
Acceleration Curve A097
00 = liner-curve
01 = S-curve (default)
02 = U-curve
03 = Inverse U-curve
Deceleration Curve A098
00 = liner-curve
01 = S-curve (default)
02 = U-curve
03 = Inverse U-curve
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.
Function
Parameters
Example Value
ALT Acceleration Time A092 2.50 seconds

Method to switch to
ALT Accel / Decel
A094
00 = Switching by input [2CH]
(configure available digital input function to 09: 2CH)
01 = Switching by frequency break point
02 = Switching by direction reversal
Accel to ALT Accel break point A095 15.00 Hz
Decel to ALT Decel break point A096 15.00 Hz
