Constant speed. The Accel. /Decel. Speed of the UP/DOWN Key
Settings 0.01~1.00Hz/ms
These settings are used when multi-function input terminals are set to 19/20. Refer to Pr.02-09 and
02-10 for the frequency up/down command.
Pr11-00, Bit7=1, frequency command is not saved. The frequency command returns to zero when
the drive stops, and the display frequency is 0.00Hz. The frequency command increase/decrease by
using Up/Down key is effective only when the drive is at Running status.
Pr.02-09 set to 0: it will increase/decrease frequency command (F) by the setting of
acceleration/deceleration (Pr.01-12~01-19)
Pr.02-09 set to 1: use multi-function input terminal ON/OFF to increase/decrease the frequency
command(F) according to the setting of Pr.02.10(0.01~1.00Hz/ms).
Digital Input Response Time
Settings 0.000~30.000 sec
This parameter is used to set the response time of digital input terminals FWD, REV and MI1~MI8.
It is used for digital input terminal signal delay and confirmation. The delay time is confirmation time
to prevent some uncertain interference that would cause error in the input of the digital terminals.
Under this condition, confirmation for this parameter would improve effectively, but the response
time will be somewhat delayed.
When using MI8 as encoder pulse feedback input, this parameter will not be referred.
