5. OPERATION
5-2
5.1 Power On
Switch power on after making sure that the unit has been installed and wired properly and that the
start signal is OFF.
The LEDs and POWER lamp of the operation panel are lit.
NOTICE
If the LEDs do not come on, check the following:
•
There is no contact fault in the connection of the operation panel and the drive unit;
•
The jumper across the DC reactor connection terminals P/+-P1 is fitted properly; and
•
The jumper across the control circuit power supply terminals R1-S1 is fitted properly.
5.2 Parameter Setting
5.2.1 Setting of the operation mode parameter
Depending on the start signal (forward rotation command, reverse rotation command, stop
command) and speed setting signal input method, you may need to set the parameter.
Choose the used operation mode in Pr. 79 [Section 8.2].
5.2.2 Confirmation of the basic operation parameters
To meet various applications, a wealth of parameter functions are available for the drive unit. The
drive unit is designed to perform simple variable-speed operation using the parameter values set
before shipment from the factory. Depending on the specification conditions of the load (machine),
however, some parameter values may need to be checked and changed.
The parameters marked
BASIC
in the table of contents of Chapter 8 PARAMETER FUNCTIONS
are the basic operation parameters whose values are recommended to be checked prior to
operation. Set them to values which match the specification conditions of the load.
