 Linear Servomotors
You can calculate the settings for the electronic gear ratio with the following equation:
When Not Using a Serial Converter Unit
Use the following formula if the linear encoder and SERVOPACK are connected directly or if a
linear encoder that does not require a Serial Converter Unit is used.
