1.2 Startup
When switching the power on for the first time, follow the startup procedure below.
The setting of the filter parameter might become necessary for LEFB25S, and confirm paragraph 7.6,
please.
Refer to the “Driver operation manual” for wiring method and detailed procedure.
1)CC-Link cable (LECSC), SSCNETIII cable (LECSS)
2)When using test operation mode (JOG operation), the LECSC and LECSS need the
MR-Configurator.

Check the surrounding environment (cable routing and
impurity such as wire off cuts or metallic dust) of the driver
and the servo motor.
Follow the procedure shown in the "Driver Operation
Manual" to supply power to the product.
Check the wiring of the input and output signals and
cables1) according to the procedure shown in the "Driver
Operation Manual".
Set the parameters as necessary, such as selecting the
control mode and each control value.
Follow the procedure shown in the "Driver Operation
Manual" to supply power to the product.
Operation with a vibration might be done according to the
condition. In that case, adjust gain. (Refer to section 1.3 &
7.6)
Gain tuning
Check if the cables to the driver and actuator are
connected correctly.

1.3 Gain tuning
Here are the steps for basic gain tuning.
Refer to the “Driver operation manual” for details and for tuning methods other than shown below.
●For LECSA (Pulse input / Positioning)
A. Adaptive filter II
Set filter parameter In LEFB25S2S. Refer the setting method of paragraph 7.6 driver's gain filter
parameter value to the setting method of filter parameter value.
B. One-touch tuning
During motor driving, push “AUTO” button on the front of the driver for three seconds.
When display panel becomes “ ”, push “AUTO” button again.
⇒The gain (including filter, etc) is adjusted automatically.
When the error occurs, refer to the “Driver operation manual”.
C. Auto tuning (Mode1)
Do this operation, if you are not satisfied with the result of “One-touch tuning”.
Set parameter No.PA08 “001”. Afterwards, do 1 and 2 alternately.
1. Reduce value of parameter No.PA09 to be less than present value.
2. Operate and ascertain the situation.
⇒The gain is adjusted automatically.
●For LECSB (Pulse input), LECSC (CC-Link), LECSS(SSCNETIII)
A. Auto tuning (Mode1)
Set parameter No.PA08 “0001”. Afterwards, do 1 and 2 alternately.
1. Reduce value of parameter No.PA09 to be less than present value.
2. Operate and ascertain the situation.
⇒The gain is adjusted automatically.
B. Auto tuning (Mode2)
Do this operation, if you are not satisfied with the result of “Auto tuning(Mode1)”.
Set parameter No.PA08 “0002”. Afterwards, do 1 and 2 alternately.
1. Reduce value of parameter No.PA09 to be less than present value.
2. Operate and ascertain the situation.
⇒The gain is adjusted automatically.
C. Adaptive filter II
Set parameter No.PB01 “0001” and drive the motor.
⇒The filter is adjusted automatically.
1)The auto tuning mode 1 may not be performed properly if the following conditions are not satisfied.
・Time to reach 2,000rpm is the acceleration/deceleration time constant of 5[s] or less.
・Speed is 150rpm or higher.
・Load to motor inertia is 100 times or less.
・The acceleration/deceleration is 10% or more of the rated torque.
2)In LECSA, load moment of inertia ratio doesn't become a fit but because the auto-tuning mode doesn't
operate when driving in low speed, operation might become unstable.
Please set increasing the speed until the auto-tuning mode operates or load moment of inertia ratio to a
proper value (About 50 times) manually. Whether to lighten the load in that case
3)Please set load moment of inertia ratio to about 50 times after it sets it to auto-tuning Mode 2 when you
drive in low speed in LECSB, LECSC, and LECSS (state that the auto-tuning mode doesn't operate).

5. Wiring of cables / Common precautions
Warning
1. Adjusting, mounting or wiring change should never be done before shutting off the power
supply to the product.
Electrical shock, malfunction and damaged can result.
2. Never disassemble the cable. Use only specified cables.
3. Never connect or disconnect the cable or connector with power on.
Caution
1. Wire the connector securely. Do not apply any voltage to the terminals other than those
specified in the product manual.
2. Wire the connector securely.
Check for correct connector wiring and polarity.
3. Take appropriate measures against noise.
Noise in a signal line may cause malfunction. As a countermeasure, separate high voltage and low
voltage cables, and shorten wiring lengths, etc.
4. Do not route wires and cables together with power or high voltage cables.
The product can malfunction due to interference of noise and surge voltage from power and high
voltage cables to the signal line. Route the wires of the product separately from power or high voltage
cables.
5. Take care that actuator movement does not catch cables.
6. Operate with cables secured. Avoid bending cables at sharp angles where they enter the
product.
7. Avoid twisting, folding, rotating or applying an external force to the cable.
Risk of electric shock, wire break, contact failure and loss of control for the product can happen.
8. Select “Robotic type cables” in case of inflecting cable(encoder/motor/rock) repeatedly.
Refer to the “Driver operation manual” for the bending life of the bending radius of the cable.
9. Confirm proper wiring of the product.
Poor insulation (interference with other circuits, poor insulation between terminals and etc.) can apply
excessive voltage or current to the product causing damage.
[Transportation]
Caution
1. Do not carry or swing the product by the cable.
