Section H: Control Circuit Terminal Parameters
H1 Digital Inputs
• Up/Down Command (settings: Up = “10,” Down = “11”)
Allows the motor speed to be increased (Up command) or decreased (Down com-
mand) via contact closures. Requires the run command to be applied.
Notes:
1. Be sure to set Speed Reference Selection (B1-01) = “1.” When B1-01 = “0,”
Up/Down operation is disabled.
2. Upper limit speed = Maximum output speed (E1-06) × Speed Reference
Upper Limit (D2-01), if used.
3. The lower limit value is the larger of either the master Speed reference from
control circuit terminals 13 or 14, or the Speed Reference Lower Limit (D2-02).
4. With Hold Reference Memory Selection is enabled (D4-01 = “1”) and a hold
command input, the output frequency stored even after the power supply
turns OFF. When D4-01 = “0” the output frequency is not stored.
5. If the jog frequency reference is input during Up/Down operation, the jog fre-
quency reference has priority.
• Forward and Reverse JOG commands (settings: Fwd Jog = “12,” Rev Jog = “13”)
Enables forward and reverse run jog frequency commands.

Setting Description
12 When closed-run forward at jog frequency reference (D1-09).
13 When closed-run reverse at jog frequency reference (D1-09).
