Calculation Examples (For a 2,500 pulses/rotation encoder)
Calculation Example (For a 17-bit encoder)
• When an encoder with a resolution of 2,500 pulses/rotation is used, the number of internal
• Given the conditions above, the relation between the number of command pulses per Servomotor
• Make the following settings to operate with 2,000 pulses/rotation.
• Similarly, make the following settings to operate with 1,000 pulses/rotation.
• Conversely, make the following settings to increase the resolution per rotation and operate with
The setting ranges for Pn48, Pn49, and Pn4B are from 1 to 10,000, so reduction is required in the
settings.
• Use the following setting to operate at 5,000 pulses/rotation:
