Setting 3 to 5: Multi-Step Speed Reference 1 to 3
Switches multi-step speed frequency references d1-01 to d1-08 by digital inputs. Refer to
Speed Selection Using Digital
Inputs (b1-01 = 0) on page 106
for details.
Setting 6: Jog reference selection
When the speed reference is not assigned to the input terminals (b1-01 ф 1), then the Jog frequency will be activated
every time an input terminal set for the Jog frequency reference closes. Note that the speed reference priority selection in
d1-18 may disable the Jog frequency.
Table 5.10 Speed Reference Priority and Jog Frequency
d1-18 (Speed Reference
Selection Mode)
Jog Frequency
0
M ulti-speed references take priority, and the leveling speed in d1-26 is used for the Jog frequency.
Jog frequency cannot be used.
2
Jog frequency cannot be used.
3
M ulti-speed references take priority, and the leveling speed in d1-26 is used for the Jog frequency.
Setting 7: Accel/decel ramp selection 1
Switches between accel/decel times 1 (C1-01 and C1-02) and 2 (C1-03 and C1-04). Refer to
C1-01 to C1-08: Accel,
Decel Ramps 1 to 4 on page 144
for details.
