UP / DOWN Key Mode

Settings
Constant Speed, Acceleration / Deceleration Speed of the UP/ DOWN Key

Settings
 Use when the multi-function input terminals are set to 19, 20 (UP / DOWN command). The
frequency increases or decreases according to Pr. 02-09 and Pr. 02-10.
 Pr. 11-00, bit7 = 1, the frequency is not saved. The frequency command returns to zero when the
drive stops, and the displayed frequency is 0.00 Hz. At this time, the increasing or decreasing
frequency command (F) by using the UP or DOWN key is valid only when the drive is running.
 When Pr. 02-09 is set to 0: the increasing or decreasing frequency command (F) operates
according to the setting for acceleration or deceleration time (refer to Pr. 01-12–Pr. 01-19)
 When Pr. 02-09 is set to 1: the increasing / decreasing frequency command (F) operates
according to the setting for Pr. 02-10 (0.01–1.00 Hz/ms).
Multi-function Input Response Time

Settings
 Sets the response time of the digital input terminals FWD, REV and MI1–MI8.
 This function is to delay and confirm the digital input terminal signal. The time for delay is also the
time for confirmation. The confirmation prevents interference that could cause error in the input to
the digital terminals. In the meanwhile, it delays the response time though confirmation improves
accuracy.
 When using MI8 as encoder pulse feedback input, this parameter is not referred.
0: Up / down by acceleration / deceleration time
1: Up/ down constant speed (Pr. 02-10)
0.001–1.000 Hz/ms
0.000–30.000 sec.
