∗When the encoder position P184=40 is transferred, the encoder position is transferred into high word and the duration period of the pulses is transferred into low word to support a duration period measurement in the slave.

If a mixture of application purposes is undertaken, e.g. master P184=44 (nominal value) and slave with encoder coupling, then the slave must be informed using P188=140 (in such cases only the high word is processed).

Application examples:

								1st unit: Master	Slave
Coupling of several axes to one								COMPAX XX60	COMPAX XX60
encoder; HEDA distributes the signals								COMPAX XX70 (P31=1)	COMPAX XX70
								Encoder input	(P31=9)
Master			Slave 1			Slave 2
								P184=40 (encoder	P188=40
								position+duration	(encoder input;
								period)	duration period
								P188=40	available)
I2	O1/O3			O1/O3			O1/O3

		SSK15			SSK14		BUS2/01	P98 and P143 must have the same
								values for master and slave!

								COMPAX XX70	P188=140
Master			Slave 1			Slave 2
									Setting P143 =
								P184=44 (nominal
									16384
								position value) or	(¼ of the increments
								P184=45 (actual	are always in P143
	O1/O3			O1/O3			O1/O3
								position value)	as quadrupling
								P188=0	occurs during
		SSK15			SSK14		BUS2/01		encoder inputs)

Note: There is a time misalignment between master and slave of 2ms; Remedy: activate identical program sets together using "Fast start".

40P143s: parameter P143 of the slave

P143M: parameter P143 of the master
