Note 1. For the MR-RB137. For the MR-RB137, three units are used as one set (permissible wattage: 3900W).
2. When using the Power factor improving DC reactor, disconnect the short bar across P
3. Make up a sequence that turns off the drive unit forced stop (EM1) and the converter unit forced stop (EM1) at the same time.
4. Attach connector for magnetic contactor control (CNP1) on the converter unit. Unattached state may cause an electric shock.
5. For specifications of cooling fan power supply, refer to section 13.3.8.
POINT
The converter unit controls the main circuit magnetic contactor.
When making CNP1 invalid, set "0000" in parameter No.PA02.
(Refer to section 13.5.)
Always connect a protection coordination cable (MR-J3CDL05M) and a
termination connector (MR-J3-TM). When they are not connected properly,
the servo-on may not be turned ON.
For the control power supplies of the converter unit and the drive unit, always
turn ON or OFF at the same time.
