(5) Connection digital encoder 3 Channels + 2 Freeze (TTL Line Driver / push pull) (DE)
Technical specication:
Channels ������������������������������� A+ A-, B+ B-, Z+ Z-, differential line drivers.
Management of loss of encoder signals (via software).
Max frequency �������������������������� 100 kHz (check the number of encoder impulses according to the maximum speed)
Number of impulses ���������������������� min 128, max 16384 (default 1024)
Electrical interface ������������������������ TTL (ref. GND) Ulow ≤ 0.5 V Uhigh ≥ 2.5 V
Load capacity ��������������������������� 13 mA @ 5.5 V (Zin 300Ω)
Programmable internal power supply ���������� min +5.2 V, max +6.1 V (default + 5.2 V) − Imax 150 mA.
The internal power supply of the encoder can be selected from the keypad (ENCODER CONFIG
menu, parameter Encoder supply (PAR 2102) to balance the loss of voltage due to the length of
the encoder cable and load current.
PAR 2102 Encoder supply range: min=5.2V, max= 6.1V, step of 0.1V; default=5,2V.
The encoder supply voltage will be rounded off to the nearest value among those 4 values avail-
able via hw: 5.2V / 5.5V / 5.8V / 6.1V.
Cable length ���������������������������� max 50m
