Safety Information
Safety Information
Read and follow all safety instructions in this manual precisely to avoid unsafe
operating conditions, property damage, personal injury, or even death.
Safety symbols in this manual
Danger
Indicates an imminently hazardous situation that, if not avoided, will result in severe
injury or even death.
Warning
Indicates a potentially hazardous situation that, if not avoided, could result in injury or
even death.
Caution
Indicates a potentially hazardous situation that, if not avoided, could result in minor

Safety Information
Caution
• Be careful when handling the CMOS components of the option card. Static charge
may cause malfunctioning of the product.
• Turn o󰀨 the inverter before connecting communication cables. Failure to do so can
cause communication errors or damage.
• Ensure that the inverter and the option card connector are correctly aligned and

4.1 Option Card Installation
Install the product on the board inside the inverter in the following order:
Note
Depending on the product family, the number of bolts on the front cover and the position
and shape of the board may vary.
Refer to 1.2 Names of Parts in the S300 Inverter User Manual for more details.
1 Cut o󰀨 the power supply of the inverter.
2 Unscrew the xing bolts on the front cover and disassemble it.
• Disassemble by unscrewing the xing bolts of the front terminal cover on 400 V
products with a capacity of 185-220 kW.

Ground
Note
• When the axis connection (coupling angle, center of two shafts, etc.) is unstable,
torque pulsation (ripple) occurs, causing vibrations in accordance with the motor
rotation when operating at a constant speed.
• If you use a line drive type encoder, you can use it within 50 meters in the following
conditions: However, available distance may change according to encoder, encoder
line, or installation environment.
Encoder Cable
ROTARY ENCODER UL 2464 AWG 20x6C
• Check the wiring distance (m) of the encoder manufacturer if you use an open
collector type of encoder. Using wiring distance out of specications provided by the
encoder manufacturer may cause a damage to the encoder.

9
Installing the Inverter
Caution
• Make sure to use shield type twisted pair cables.
• Make sure to install the encoder so that it rotates at the same speed as the motor
shaft.
e.g. the half-loaded side shaft of the motor and the opposite side shaft of the motor of
the traction machine
• When there is a slip between motor shaft and encoder shaft, the motor may not work
or vibrate severely.
• Try not to install the encoder signal lines with the power line of the inverter. Noise
from the encoder output signals may impact the power line.

Troubleshooting
5 Troubleshooting
Refer to the following when a trip occurs while using the encoder:
Items Cause Remedy
Encoder No Connect
A trip occurs when you set the
ENC-16 (Wire Check Trip En)
code to 1 (Yes) and wiring
between the encoder and
encoder option is incorrect.
Set the ENC-16 (Wire Check
Trip En) code to 0 (No) and
check the wiring between the
encoder and encoder option.
