Part 5: Review on Replacement of MR-J2S-30 kW or Higher Capacity Models with MR-J4-DU_
5 - 8
1.5 Magnetic Contactor Control Connector (CNP1) [Exclusively for MR-J4-DU_]
Note
Connect a magnetic contactor wiring connector to the converter unit. CNP1-1 and
L11 are always in conduction. Leaving the connector disconnected can cause an
electric shock.
POINT
The J2S series comes with no magnetic contactor control connector.
Enabling the magnetic contactor output shuts off the main circuit power supply automatically when the drive
unit activates an alarm.
Setting converter unit parameter [Pr. PA02] to "_ _ _ 1" (the initial value) enables the magnetic contactor
output.
(1) When the magnetic contactor drive output is enabled
Connecting the magnetic contactor control connector (CNP1) to the coil of a magnetic contactor enables
the control of the magnetic contactor.
CNP1 connection internal diagram
Note 1. Use a step-down transformer when the converter unit and drive unit are 400 V
class and the coil voltage of the magnetic contactor is 200 V class.
2. Bus voltage decreases according to the voltage and operation pattern of the main
circuit, and there may be a shift in dynamic brake deceleration during forced stop
deceleration. If dynamic brake deceleration is not desired, delay the time to turn
off the electromagnetic contactor.
3. If instantaneous power failure or any other problem lowers the voltage of L11 or
L21, the magnetic contactor turns off.
