OVERVIEW: This is a basic installation and commissioning steps that must be adhere for quick installation and commissioning.
Check the following after receiving the product. If found
abnormalities, please contact the local dealer or Kruger office.
1.1 Check if the packing box is damaged.
1.2 Check if the interior surface of the packing box is abnormal.
For example, in wet condition or whether the enclosure of the
VFD is damaged or cracked.
1.3 Check if the accessories inside the packing box are complete
(including the manual and keypad).
1.4 Check if the VFD nameplate is consistent with the model
identifier on the exterior surface of the packing box and your
purchased model.
Check the following before VFD installation.
2.1 Ensure that the grid voltage meets input power of VFD.
2.2 Ensure that the output power from VFD is matched with the
motor spec.
2.3 Ensure that the environments of installation area are not over
the VFD specified limits.
2.6 Ensure that all grounding systems are properly grounded
according to the requirements of the VFD.
2.7 Ensure that the external connection terminals of the VFD are
tightly fastened and the torque on the bolts are appropriate.
2.8 Ensure that there are screws, cables, or other conductive
items are cleared from the VFD. If no, clear them out.
Check the following after the
VFD installation.
2.4 Ensure that the correct
accessories are selected for
the VFD. The accessories
are correct and properly
installed, and the
installation cables meet the
requirements of all
components (including the
reactor, input filter, output
reactor, output filter, DC
reactor, braking unit and
braking resistor).
2.5 Ensure that all control
cables and power cables are
run separately and the
routing complies with EMC
requirements.
Complete the basic commissioning below before the actual use
of the VFD. (See more details in page no. 2)
CAUTION: The K320 should ONLY be installed by a
qualified electrician.
DANGER! Improper wiring can and will cause bodily
harm as well as damage to the equipment.

3.1 MOTOR SETTING & AUTO TUNING 3.2 CONTROL METHOD SETTING
1. Select the motor type
Push Manu => Parameter setting => Motor and Encoders
parameter setting => Motor1 param => P02.00 motor type
(0: Asynchronous motor, 1: Synchronous motor)
2. Set motor parameters follow Motor’s nameplate
- Asynchronous motor_P02.01 to P02.05
Example of setting
- Synchronous motor _P02.15 to P02.19
Example of setting
3. Auto tuning
De-couple the load from motor before start autotuning.
Push Manu => Motor parameters auto tuning =>
1: Rotary auto tuning => Push RUN to start auto tuning
=> Waiting until tuning completed
Note: If cannot be de-coupled motor from the load,
please select to perform 2: Static autotuning.
4. Check rotating direction
Push Jogging for 5sec to run motor and check whether
the motor rotational direction is correct. If not, change the
rotation direction by swapping UW wires of the motor.
or change P00.13 from 0 to 1: Run in reverse direction.
