Notes on encoder supply directly from the subsequent electronics:
(Parameter P2: FROM CUSTOMER)
1. Trouble-free functioning of subsequent electronics with 11µApp and 1Vpp encoder interfaces cannot be
guaranteed due to signal shifts of the subsequent electronics!
2. The encoder voltage of the subsequent electronics is fed directly to the encoder without being changed
by PWM 8; it cannot be altered.
3. There is no current limitation for the encoder voltage.
4. The power consumption of the subsequent electronics for the encoder supply is only slightly higher than
that of the encoder. About 10 mA are required for the voltage monitor of the subsequent electronics.
Parameter P3: U-MSYS LIMIT
Parameter P3 defines the maximum limits for the encoder voltage. By switching off the
U-MSYS limit the encoder voltage can be set in the range of 9V ±1V.
Caution:
Standard encoders are operated with a voltage of 5V ± 5%.
Special feature of HTL interface boards:
When using the HTL interface board, parameter P3 is not available!
In the EXPERT MODE the encoder voltage can only be set with the soft keys
parameter P2 is set to FLOATING.
Parameter P4: EXPERT MODE
If parameter P4 is set to SAVE, the EXPERT MODE is reactivated after power interruption;
if it is set to NOT SAVE, the EXPERT MODE must be reactivated each time power is switched on.
Parameter P5: EVALUATION
In parameter P5 the edge evaluation of the UNIVERSAL COUNTER (PWM 8 MODE UNIVERSAL
COUNTER) is set. It defines how many edges per signal period of incremental signal 1 and incremental
signal 2 are transferred to the UNIVERSAL COUNTER and used for measurement of the frequency.
In the PWM 8 MODE: DETERMINE PULSE NUMBER the evaluation is automatically set to 1-FOLD. The
EVALUATION is displayed next to the headline of the UNIVERSAL COUNTER:
Parameter P6: COUNTING MODE
Parameter P6 defines the COUNTING MODE of the last digit of the UNIVERSAL COUNTER.
[ON (6 VOLTS), OFF (9 VOLTS)]
The measured object may be destroyed by overvoltage!
[NOT SAVE, SAVE]
[1-FOLD, 2-FOLD, 4-FOLD]
[0-1-2, 0-2-4, 0-5-0]
