• These objects set the gear ratio.
• Set the numerator of the electronic gear in the object for sub-index 01h (Motor revolutions). If the set
value is 0, the encoder resolution will be set as the numerator.
• Set the denominator of the electronic gear in the object for sub-index 02h (Shaft revolutions).
• Set the gear ratio to between 1/1,000 and 1,000. If the gear ratio is out of range, an Object Setting
Error (Error No. 93.0) will occur.
• If the set value of Motor revolutions is 0, the encoder resolution will be set as the numerator, even for
fully-closed control.
• If you are mapping the Reference Position for CSP (4020 hex) to the PDO, be sure to set the
electronic gear ratio to 1:1.
Unless set to 1:1, a Function Setting Error (Error No. 93.4) will occur.
• Refer to 7-6 Electronic Gear Function on page 7-21 for details.
Precautions for Correct Use Precautions for Correct Use
• The electronic gear function is not supported for unit version 2.0. Use the G-series Servo Drive in
the setting of 1:1.
