8.5.5 Additional Running Control
S3.30 Forward and reverse rotation dead zone time
Setting range 0.0 ~ 60.0s
Minimum unit 0.1s
Factory default 4.0s
S3.31: Reserved
S3.30 represents the waiting time when the frequency converter switches from
forward / reverse rotation to reverse / forward rotation. See the figure below for
more information:
Fig. 8-28: Forward and reverse rotation dead zone time
S3.32 UP / DOWN set velocity
Setting range 0.10 ~ 100.0 Hz/s
Minimum unit 0.01 Hz/s
Factory default 1.00 Hz/s
S3.33 UP / DOWN terminals initial frequency
Setting range 0.00 Hz ~ [b1.06]
Minimum unit 0.01 Hz
Factory default 0.00 Hz
Used to change the output frequency. When [b1.00] / [b1.16] = 4, the UP /
DOWN control is activated as the command source. In this mode, the output fre-
quency can be adjusted easily with UP, DOWN and zeroing terminals. Please fol-
low the following steps to adjust the output frequency.
1. Set [b1.00] / [b1.16]=4.
2. Define any 3 external control terminals in parameters E0.01 ~ E0.05 with
one set to 9 "Frequency increment UP command", one set to 10 "Frequen-
cy decrement DOWN command", and another set to 11 "Zeroing of external
terminal frequency setting".
