Efficient Networks S120 manual Setting the sampling times

Basic information about the drive system 12.12 System sampling times

For p0092 = 1, the sampling times are pre-assigned so that isochronous operation together with a control is possible. If isochronous operation is not possible due to incorrect sampling time settings, then an appropriate message is output (A01223, A01224). Before the automatic configuration, parameter p0092 must be set to "1" in order that the sampling times are appropriately pre-set.

Note

Any change to the preset sampling times should only be performed by experts.

12.12.2Setting the sampling times

Introduction

Setting the sampling times via p0112

The sampling times for:

●Current controller (p0115[0])

●Speed controller (p0115[1])

●Flux controller (p0115[2])

●Setpoint channel (p0115[3])

●Position controller (p0115[4])

●Positioner (p0115[5])

●Technology controller (p0115[6])

are set by selecting the appropriate values in p0112 for the closed-loop control configuration and are copied to p0115[0...6] depending on the performance levels required. The performance levels range from xLow to xHigh.

The sampling times are shown in the following table.

Table 12-22 For Active Infeed, the sampling time is set using p0112 (p0112 = 1 not for p0092 = 1)

p0112	p0115[0]	p0115[1]	p0115[2]	p0115[3]		p0115[4]	p0115[5]	p0115[6]
1: xLow	400	-	-	1600	-		-	-
2: Low	250	-	-	2000	-		-	-
3: Standard	125	-	-	2000	-		-	-
4: High	125	-	-	1000	-		-	-
5: xHigh	125	-	-	500	-		-	-

Table 12-23 For Smart Infeed, the sampling time is set using p0112 (p0112 = 1 not for p0092 = 1)

p0112	p0115[0]	p0115[1]	p0115[2]	p0115[3]		p0115[4]	p0115[5]	p0115[6]
1: xLow	400	-	-	1600	-		-	-
