rotary motors by default. If a linear motor is configured, the drive sets a 2.67
MHz pre-quadrature maximum input encoder frequency by default.

The ENCFLT command increases the default maximum pre-quadrature

encoder frequency from 1.02 MHz to 2.67 MHz or 5 MHz. This allows users
to take advantage of the higher input frequency, if necessary, at the expense
of some noise immunity.

Note:

This command does not take effect until you cycle power to the drive

or send the RESET command.

The ENCOFF command specifies the encoder offset. All standard (non-smart)

Parker encoders have an encoder offset of 0 degrees. The smart encoders
store the encoder offset in the motor, which the drive reads (and stores in the
ENCOFF parameter) upon power-up. The offset can vary from
–180 degrees (corresponding to ENCOFF=-32768) to +180 degrees
(corresponding to ENCOFF = 32767).

Note:

To convert from degrees to counts, just multiply the offset in degrees

by 182.044.

The ENCPOL command reverses the encoder counting direction.
You can reverse the encoder polarity if the encoder input is counting in the
wrong direction (for example, using a custom motor). This reverses the
encoder counting direction without having to change the actual wiring to the
encoder input.
