Limit the Direction of Rotation
Prohibition of reverse operation b1-04
When reverse run disabled is set, reverse run command
from the control circuit terminal or digital operator cannot
be enabled. Use this setting for applications where reverse
run will not be used (fans, pumps, etc.).

Description
Note: When an inverter forward run command is given, the motor output shaft
rotates in the counterclockwise (CCW) direction viewed from the motor
at the load side (output shaft side).
Multi-Step Speed Selection
Master frequency reference selection b1-01
Operation method selection b1-02
Constant access level A1-01
Frequency reference d1-01 to 16
Jog frequency reference d1-17
Multi-function input H1-02 to 10
Terminal A2 function selection H3-09
Terminal A3 function selection H3-05
By combining 16-step frequency references, one jog frequency reference and
multi-function terminal function selection, up to 17 steps of speed variations
can be set step by step. (The following shows an example of 9-step speed.)
Operation method selection b1-01=0, b1-02=1
Constant access level A1-01=2
The range where multi-step speed frequency reference can
be set or read depends on the program mode as follows:
QUICK :
Up to 5 steps of speed variations can be set or read.
d1-01, 02, 03, 04, 17
ADVANCED: Up to 17 steps of speed variations can be set or read.

＊ 1 When the preset reference 1 is b1-01= 0, constant setting value (d1-01) is applied; when
b1-01 = 1, the analog command set by control circuit terminal A1 is applied.
＊ 2
When the preset reference 2 is H3-05 = 2, the analog frequency reference input through terminal
A3 is applied; when the setting is H3-05 = 1F, constant setting value (d1-02) is applied.
＊ 3 When the preset reference 3 is H3-09 = 3, the analog frequency reference input through terminal
A2 is applied; when the setting is H3-09 = 0, constant setting value (d1-03) is applied.
Run at Low Speed
Jog frequency reference d1-17
Multi-function input H1-01 to 05
Set Jog frequency in Multi-function contact input terminals
S3 to S12. Next, input the Jog frequency reference and the
forward (reverse) run command. Jogging can be performed
with the jogging frequency set in d1-17. When multi-speed
reference 1 to 4 is set along with Jog reference, the Jog
reference has priority.
The same operation can be also accomplished by the digital
operator.
