The following shows the time chart at UP/DOWN command input.

U1 =

D1 =

NOTE:

1. When UP/DOWN command is selected, the upper limit speed is set regardless of frequency reference.

Upper limit speed = Maximum output frequency (n012) 5 Frequency reference upper limit (n030)/100

Lower limit value is either frequency by Analog command from control circuit Terminals, FV, FI or frequency reference lower

limit (n031) (whichever is larger).

3. When the FWD or REV RUN command is input, operation starts at the lower limit speed without an UP/DOWN command.

4. If the jog frequency selection command is input while running by the UP/DOWN command, the jog command has priority.

Loop Test (Setting: 26)

Checks operation in the serial I/F circuit. If a fault occurs, the Digital Operator displays CE.

Procedure

Set the multi-function contact input selection (n039) after turning ON the Inverter power supply, and then turn

OFF the Inverter power supply.

Short-circuit Terminals S6 and SC, connector 2CN pins 1 and 2.

communication interface card SI-K2/P.)

Loop test is started by turning ON the Inverter power supply.

The Digital Operator displays the frequency reference after the loop test is completed satisfactorily.
