PX - Main Position
Purpose:
Reads the position of the main feedback. Upon power on, the main position is set to zero.
The PX variable accumulates the main feedback pulses. PX can count cyclically (refer to
the
XM[N] command). When the motor is off, PX may be used to set a value for the
position counter by typing PX=n. To program the position while the motor is on, refer to
the
HM[N] command.
Attributes: Type: Parameter/Status report, Integer
Source: Program, RS-232, CANopen
Reset value: 0, Volatile
Restrictions: MO=0
Range:
See Notes below
Unit modes: All
SimplIQ: Similar
Notes:
PX is limited to the position counter range .
If PX exceeds the modulo range, it will be automatically set to a value within that
range.
PX counts in the direction defined by CA[16]. If CA[16] is modified, PX will not
change, but position counting will be continued in the other direction. To ensure
proper commutation, CA[16] must be modified in conjunction with the motor
direction (CA[25]).
