• Do not use phase correction capacitors.
• If using a contactor between the drive and motor, it should never be operated when the drive is outputting a voltage. Operating while there is
voltage output can cause large peak currents, thus tripping the over current detection or damage the drive.
Ground Connection
Take the following precautions when grounding the drive.
• Never share the ground wire with other devices such as welding machines, etc.
• Always use a ground wire, that complies with electrical equipment technical standards. Keep ground wires as short as possible. Leakage current
is caused by the drive. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground
terminal of the drive will become unstable.
• Make sure the ground conductor complies with technical standards and local safety rules. The drive has an EMC filter installed and the leakage
current exceeds 3.5 mA. Therefore according to IEC61800-5-1, a protective earthing conductor with a cross section of at least 10 mm
2
(Cu) or 16
mm
2
(Al) must be used, or automatic power supply interruption in case of discontinuity of the protective earthing conductor must be provided.
• When using more than one drive, do not to loop the ground wire.
Control Circuit Wiring Precautions
Consider the following precautions for wiring the control circuits.
• Separate control circuit wiring from main circuit wiring and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC (contact output) from wiring to other control circuit terminals.
• For external control power supply use a UL Listed Class 2 power supply.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults.
• Connect only Digital Operator JVOP-180 (LCD), JVOP-182(LED) or JVOP-181 (USB Copy Unit) to external RJ45 connector on drives model
code CIMR-...-0081. Do not connect any other device to the RJ45 connnector.Drive or external device may be damaged.
• Drives model code CIMR-...0080 can be connected to PC by using JVOP-181(USB Copy Unit). Use the RJ45 connector where the Digital
Operator is connected.
• Ground the cable shields with the maximum contact area of the shield and ground.
• Cable shields should be grounded on both cable ends.
• If flexible wires with ferrules are connected they might fit tightly into the terminals. To disconnect them, grasp the wire end with a pair of pliers,
release the terminal using a straight-edge screw driver, turn the wire for about 45
and pull it gently out of the terminal. For details, refer to the
Technical Manual. Use this procedure for removing the wire link between HC, H1 and H2 when the Drive Disable function is utilized.
Main Circuit Terminals
Control Circuit Terminals
The figure below shows the control circuit terminal arrangement. The drive is equipped with screwless terminals.
There are three DIP switches, S1 to S3, located on the terminal board
