• Rotation direction of the gear output shaft
The relationship between the rotation direction of the motor shaft and that of the gear output shaft changes as follows,
depending on the gear type and gear ratio.
Type of gear
TH geared
PS geared
All gear ratios
PN geared
Harmonic geared All gear ratios
• Do not perform push-motion operation with geared types.
Doing so may cause damage to the motor or gear part.
• Saving data to the non-volatile memory
Do not turn off the power supply while writing the data to the non-volatile memory and 5 seconds after the
completion of writing the data. Doing so may abort writing the data and cause a EEPROM error alarm to generate.
The non-volatile memory can be rewritten approximately 100,000 times.
• Motor excitation at power ON
The motor is excited when the power is on. If the motor is required to be in non-excitation status when turning on the
power, assign the C-ON input to the direct I/O or network I/O.
• Overvoltage alarm by regeneration energy
The overvoltage alarm will generate depending on the operating condition. When an alarm is generated, review the
operating conditions.
• Note on connecting a power supply whose positive terminal is grounded
The power supply connector (CN1), data edit connector (CN3) and RS-485 communication connector (CN6/CN7)
of the driver are not electrically insulated. When grounding the positive terminal of the power supply, do not connect
any equipment (PC, etc.) whose negative terminal is grounded. Doing so may cause the driver and these equipment to
short, damaging both. Use the OPX-2A to set data, etc.
