ONFIGURATIONS
Performs the following steps to set factors in order to configure the drive starting from the encoder
to the linear actuator.
Position encoder resolution motor revolutions and Position encoder resolutions encoder
increments perform the calculation of resolution of the encoder mounted on the motor.
𝑃𝑜𝑠𝑖𝑡𝑖𝑜𝑛 𝑒𝑛𝑐𝑜𝑑𝑒𝑟 𝑟𝑒𝑠𝑜𝑙𝑢𝑡𝑖𝑜𝑛 =
𝑃𝑜𝑠𝑖𝑡𝑖𝑜𝑛 𝑒𝑛𝑐𝑜𝑑𝑒𝑟 𝑟𝑒𝑠𝑜𝑙𝑢𝑡𝑖𝑜𝑛𝑠 𝑒𝑛𝑐𝑜𝑑𝑒𝑟 𝑖𝑛𝑐𝑟𝑒𝑚𝑒𝑛𝑡𝑠
𝑃𝑜𝑠𝑖𝑡𝑖𝑜𝑛 𝑒𝑛𝑐𝑜𝑑𝑒𝑟 𝑟𝑒𝑠𝑜𝑙𝑢𝑡𝑖𝑜𝑛 𝑚𝑜𝑡𝑜𝑟 𝑟𝑒𝑣𝑜𝑙𝑢𝑡𝑖𝑜𝑛𝑠
The drive counts every edge of the two encoder channels, so there is a factor 4 between encoder
resolution and motor revolutions.
EXAMPLE: the application has an encoder with 2048 pulses for round, Position encoder resolutions
encoder increments must be set to 8192 and Position encoder resolution motor revolutions must be
set to 1.
