62.20 POS ACT OFFSET
Offsets all the position values used by the position system, effectively correcting the position and
revolution count signal received from the encoder. For example, this parameter can be used if a non-
zero position signal received from the encoder needs to be defined as the zero position for the
application.
For example, if this parameter is set to a value of -100, the absolute position of 100 revolutions as
measured by the encoder is interpreted as the zero position.
Notes:
• The offset takes effect upon the next power-up or when an encoder reconfiguration command is
given using parameter
• The offset will not be visible through any actual signal or other parameter.

62.21 POS COR MODE
Determines if the position change made in homing or in preset mode 2 or 3 is forced permanently into
the drive memory by saving it to parameter 62.20, or only until the next power-down.
(0) NORMAL
(1) PERMANENT
Parameters and firmware blocks
