2. INSTALLATION AND START UP
2.6 When switching power on for the first time
Before starting operation, check the following:
(1) Wiring
(a) Check that the control circuit power cable, main circuit power cable and servo motor power cable
are fabricated properly.
(b) Check that the control circuit power cable is connected to the CNP1B connector and the main
circuit power cable is connected to the CNP3 connector.
(c) Check that the servo motor power cable is connected to the drive unit CNP2 connector.
(d) Check that the base unit is earthed securely. Also check that the drive unit is screwed to the base
unit securely.
(e) When using the regenerative brake option, check that the cable using twisted wires is fabricated
properly and it is connected to the CNP1A connector properly.
(f) When the MR-J2M-70DU is used, it is wired to have the left-hand side slot number of the two slots.
(g) 24VDC or higher voltages are not applied to the pins of connector CN3.
(h) SD and SG of connector CN1A
CN1B CN3 CN4A CN4B and CN5 are not shorted.
(i) The wiring cables are free from excessive force.
(j) Check that the encoder cable and servo motor power cable connected to the drive unit are connected
to the same servo motor properly.
(k) When stroke end limit switches are used, the signals across LSP
-SG and LSN -SG are on
during operation.
(2) Parameters
(a) Check that the drive unit parameters are set to correct values using the servo system controller
screen or MR Configurator (servo configuration software).
(b) Check that the interface unit parameters are set to correct values using the interface unit display
or MR Configurator (servo configuration software).
(3) Environment
Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
(4) Machine
(a) The screws in the servo motor installation part and shaft-to-machine connection are tight.
(b) The servo motor and the machine connected with the servo motor can be operated.
