WARNING
Do not operate the switches with wet hands. You may get an electric shock.
CAUTION
Before starting operation, check the parameters. Some machines may perform
unexpected operation.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands
and parts (cables, etc.) with the servo amplifier heat sink, regenerative resistor,
servo motor, etc. since they may be hot while power is on or for some time after
power-off. Their temperatures may be high and you may get burnt or a parts may
damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can
cause injury.
4.1 Switching power on for the first time
When switching power on for the first time, follow this section to make a startup.
4.1.1 Startup procedure
Wiring check
Surrounding environment check
Axis No. settings
Parameter setting
Test operation of servo motor
alone in test operation mode
Test operation of servo motor
alone by commands
Test operation with servo motor
and machine connected
Gain adjustment
Actual operation
Stop
Check whether the servo amplifier and servo motor are wired correctly using
visual inspection, DO forced output function (section 4.5.1), etc. (Refer to
section 4.1.2.)
Check the surrounding environment of the servo amplifier and servo motor.
(Refer to section 4.1.3.)
Confirm that the axis No. settings for rotary axis setting switch (SW1) and
servo system controller are consistent. (Refer to section 3.12)
Set the parameters as necessary, such as the used control mode and
regenerative option selection. (Refer to chapter 5)
For the test operation, with the servo motor disconnected from the machine
and operated at the speed as low as possible, check whether the servo moto
r
rotates correctly. (Refer to sections 4.5)
For the test operation with the servo motor disconnected from the machine
and operated at the speed as low as possible, give commands to the servo
amplifier and check whether the servo motor rotates correctly.
Connect the servo motor with the machine, give operation commands from the
host command device, and check machine motions.
Make gain adjustment to optimize the machine motions. (Refer to chapter 6.)
Stop giving commands and stop operation.

4.1.2 Wiring check
(1) Power supply system wiring
Before switching on the main circuit and control circuit power supplies, check the following items.
(a) Power supply system wiring
The power supplied to the power input terminals (L
1, L2, L3, L11, L21) of the servo amplifier should satisfy
the defined specifications. (Refer to section 1.3.)
(b) Connection of servo amplifier and servo motor
1) The servo motor power supply terminals (U, V, W) of the servo amplifier match in phase with the
power input terminals (U, V, W) of the servo motor.

2) The power supplied to the servo amplifier should not be connected to the servo motor power supply
terminals (U, V, W). To do so will fail the connected servo amplifier and servo motor.

(c) When option and auxiliary equipment are used
1) When regenerative option is used under 3.5kW for 200V class and 2kW for 400V class
The lead between P terminal and D terminal of CNP2 connector should not be connected.
The generative brake option should be connected to P terminal and C terminal.
A twisted cable should be used. (Refer to section 11.2)

2) When regenerative option is used over 5kW for 200V class and 3.5kW for 400V class
The lead of built-in regenerative resistor connected to P terminal and C terminal of TE1 terminal block
should not be connected.
The generative brake option should be connected to P terminal and C terminal.
A twisted cable should be used when wiring is over 5m and under 10m. (Refer to section 11.2)
3) When brake unit and power regenerative converter are used over 5kW
The lead of built-in regenerative resistor connected to P terminal and C terminal of TE1 terminal block
should not be connected.
Brake unit, power regenerative converter or power regeneration converter should be connected to P
terminal and N terminal. (Refer to section 11.3 to 11.5)
4) The power factor improving DC reactor should be connected P
1 and P2 (For 11k to 22kW, P
1
and P).

Note. Always disconnect P1 and P2. (For 11k to 22kW P1 and P)
(2) I/O signal wiring
(a) The I/O signals should be connected correctly.
Use DO forced output to forcibly turn on/off the pins of the CN3 connector. This function can be used to
perform a wiring check. In this case, switch on the control circuit power supply only.
(b) 24VDC or higher voltage is not applied to the pins of connectors CN3.
(c) SD and DOCOM of connector CN3 is not shorted.

4.1.3 Surrounding environment
(1) Cable routing
(a) The wiring cables are free from excessive force.
(b) The encoder cable should not be used in excess of its flex life. (Refer to section 10.4.)
(c) The connector part of the servo motor should not be strained.
(2) Environment
Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
