· Speed Control Integral Value Reset (setting: “E”)

The speed control integral value can be reset while the inverter is running when this function is

selected. Reset is effective only when integral control selection during accel/decel (F1-07) = “0”.

Open: PI-control (speed control integral values are added.)

Closed: P-control (speed control integral values are reset by the integral time constant.)

· Up/Down Command (settings: Up = “10”. Down = “11”)

With the FWD (REV) run command entered, a change in frequency is performed by inputting the Up

or Down signals to any two contact inputs, so that operation can be performed at the desired speed.

Notes:

1. Be sure to set frequency reference selection (B1-01) = “1”. When B1-01 = “0”, Up/Down

operation is disabled.

2. Upper limit speed

= Max. output frequency (E1-04) × Frequency reference upper limit (D2-01), if used

3. The lower limit value is either the master frequency reference from control circuit terminals

13 or 14, or the frequency reference lower limit (D2-01), whichever is larger.

4. When hold reference memory selection is enabled (D4-01 = “1”) and a hold command is

input, the held output frequency is stored even after the power supply is turned OFF.

When D4-01 = “0”, the held output frequency is not stored.

5. If the jog frequency reference is input during Up/Down operation, the jog frequency ref-

erence has priority.
