Touch probe 1 TPR1

2.4 Power-on sequence

(1) Power-on procedure
1) Always wire the power supply as shown in above section 3.1 of "MR-JE-_C Servo Amplifier
Instruction Manual" using the magnetic contactor with the power supply (L1/L2/L3). Configure up
an external sequence to switch off the magnetic contactor as soon as an alarm occurs.
2) The servo amplifier receives the servo-on command in 3 s to 4 s + network initial communication
time after the power supply is switched on.
(Refer to (2) in this section.)

CN3-6 The touch probe function that executes current position latch by sensor input
can be used. For details of the touch probe function, refer to "MR-JE-_C Servo
Amplifier Instruction Manual (Network)".
