Remark:
Parameter K182 is automatically set to 0 when the controller is switched on. This parameter
cannot be saved in the controller. Writing 1 in parameter K182 starts the position capture process
even if the value was already equal to 1. To start a new position capture, the value 1 must be
rewritten in parameter K182.
Bit# 2 of monitoring M61 and bit# 30 of monitoring M63 are set to 1 when the conditions of the
digital input allow the capture of the position. They are reset (to 0) when 1 is written in parameter
K182.
13.5.1 Description of the position capture process on the digital inputs
• Set to 1 the bits of parameter K159 corresponding to the digital inputs which must be inverted.
• Set to 1 the bits of parameter K178 corresponding to the digital inputs which must be detected on a rising
edge.
• Set to 1 the bits of parameter K179 corresponding to the digital inputs which must be detected on a falling
edge.
• Set parameter K182 to 1 to execute a new position capture.
• The position controller monitors the digital inputs according to parameters K178, K179 and K159. When
one of the conditions is met, the position controller stores the position (upi) in monitoring M12 and sets to 1
bit# 2 of monitoring M61 and bit# 30 of monitoring M63 (bits of monitorings M61 and M63 are processed
every 166.67
µ
s for the DSC2P/DSC2V and 500
µ
s for the DSCDP, DSCDL and DSCDM).
• To start a new position capture, the last two points above-mentioned must be re-executed.
