2.7 Explanation of the Display
Structure of the display
Information on the encoder
Measuring range and scaling of the PHA/TV display
PHA/TV display with peak hold
(here: maximum error: +TV2)
Display field for PWM 8 modes (here: UNIVERSAL
COUNTER and frequency display)
Soft-key row for operation
Current assignment of the BNC sockets
The following information is permanently displayed:
a): Information on the encoder:
Display: The supply voltage for the encoder is switched on.
Display: The supply voltage for the encoder is switched off.
Display: Reference signal
(no reference signal available)
The reference signal is displayed;
no real-time display of the reference signal!
Display: Fault detection signal
(no fault detection signal generated)
Fault detection signal generated, (active: low); at the same time
the fault detection signal memory (ERROR) is set.
No fault detection signal generated; the fault detection signal memory
(ERROR) has been set by an earlier fault.
The fault-detection memory can be deleted by:
1. activating another PWM 8 mode
2. switching the encoder voltage off and on
3. by pressing the soft key of the INFO soft-key row.
Display of the counting direction: Encoder moves in forward direction
Display of the counting direction: Encoder moves in backward direction
The last two places (xx) of the Id.No. represent
the software version.
