3.7 Measurement Modes
Limit-Value Monitoring
The following value ranges are permitted for limit-value monitoring:
Low limit n
0 to 24 999 999 × 10
Possible Measuring Ranges with Error Indication (Number of Pulses per Encoder Revolution = 60)
Function of the Digital Input
For the "Function DI" parameter, select one of the following functions for the digital input:
● Input
● HW gate (see section "Gate Functions in Measurement Modes (Page 185)")
Function of the Digital Output DO1
For the "Function DO1" parameter, select one of the following functions for the DO1 digital
output:
● Output (no switching by the limit-value monitoring)
● Measured value outside the limits
● Measured value under the low limit
● Measured value over the high limit
(see section "Behavior of the Outputs in Measurement Modes (Page 186)")
Function of the Digital Output DO2
● Output
(see section "Behavior of the Outputs in Measurement Modes (Page 186)")
