Installation and
Mounting Install the Inverter according to the installation conditions. - 1
S Ensure that the installation conditions are met.
Wiring and Connec-
tion Connect to the power supply and peripheral devices. - 1
S Select peripheral devices which meet the specifications and wire correctly.
Power ON Carrying out the following pre-connection checks before turning ON the power supply: - 4
S Always ensure that a power supply of the correct voltage is used and that the power input terminals (R, S, T)
are wired correctly.
200 V class: 3-phase 200 to 230 VDC, 50/60 Hz
400 V class: 3-phase 380 to 460 VDC, 50/60 Hz
S Make sure that the Motor output terminals (U, V, W) and the Motor are connected correctly.
S Make sure that the control circuit terminals and the control device are wired correctly. Make sure that all control
circuit terminals are turned OFF.
S When using a PG Speed Control Card, ensure that it is wired correctly.
S Set the motor to no-load status, (not connected to the mechanical system).
Having conducted the above checks, connect the power supply.
Check the Display
Status Check to be sure that there are no faults in the Inverter. - 4
1
S If the display at the time the power is connected is normal, it will read as follows:
Data Display: Frequency Ref
S When an fault has occurred, the details of the fault will be displayed. In that case, refer to Section 9 Maintenance
Operations.
Setting the Input Volt-
age
Set the Inverter input voltage (E1-01) to the correct voltage. - 5
Set the Motor Set the proper motor protection (E1-02). - 6
Autotuning Execute autotuning for motor unit separately before open-loop vector control or Flux vector control operation.. - 6
2 S When autotuning is executed, motor constants are set automatically.
No-load Operation Start the no-load motor using the Digital Operator. - 8
S Set the frequency reference using the Digital Operator and start the motor using key sequences.
Actual Load Opera-
tion
Connect the mechanical system and operate using the Digital Operator. - 9
S When there are no difficulties using the no-load operation, connect the mechanical system to the motor and oper-
ate using the Digital Operator.
Operation Basic Operation: Operation based on the basic settings required to start and stop the Inverter. NO TAG
Advanced Operation: Operation which uses advanced functions. NO TAG
S For operation within standard constants select “Basic Operation.”
S To use the various applied functions such as, direct current control braking, speed search, S-curve acceleration/
deceleration, slip compensation, torque compensation, and select “Advanced Operation” in combination with
“Basic Operation.”
* 1. It is sometimes necessary to initialize constants after checking the display status.
Initializing Constants Initialize the constants. - 4
S Check the Inverter capacity setting (kVA) in o2-04 before replacing the controller PCB with a spare.
* 2. When motor cannot be disconnected from the load, motor constants can be set by calculations. Contact your YASKAWA repre-
sentatives for details.
