· 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.
