Size 40 Dual (Multi-turn) DigiSolver

3. Multi-Turn:

18-bit Binary over 64 turns; 15-bit BCD or Standard Gray over 32 turns; Size 40 (E5N series) or explosion­proof housing (E8N series). Internal gear train ratios of 64:1 or 32:1.

Single- or Multi-Turn Operation

The DigiSolver is an absolute encoder; that is, it keeps track of the exact shaft position even during power outage or switching-off the machine. At power-up, the DigiSolver's output will indicate the exact shaft position, even if the machine moved during the power outage.

In a single-turn operation, the machine cycle is completed during one complete revolution of the transducer shaft, whereas in a multi-turn operation the transducer shaft needs to make more than one turn for a complete machine cycle.

Specifications

ELECTRICAL
Input Power:
    Voltage: 5 VDC +/- 5%, or 8-30 VDC
    Current: 0.55 A, Single-turn; 0.75 A, Multi-turn
Power-on Settling Time:
    For 130 ms after power is turned ON, the encoder
    output is frozen as follows:
    T & N: all zeros
    P & C: all ones
    After 130 ms, the DigiSolver reads the TRUE position.

OUTPUT DRIVERS:
T: Tristate (Multiplexing): TTL (74LS 645), high logic TRUE
    Logic True: 2V @ 15 mA, 20 mA leakage when tristated
    Logic False: 0.35 V @ 24 mA, 0.4 mA leakage when
    tristated MUX input: Low active, TTL level
P: Source Transistor: Vmax = 30 V, high Logic TRUE
    (Sprague UDN-2981A)

    Logic TRUE: Transistor ON, 1.7 V drop @ 100 Ma
    Logic FALSE: Transistor OFF, 0.2 mA leak. @ 50 V.
    On ES the P-type outputs are short-circuit-proof and are
    rated 20 mA @ 50 VDC
N: Sink Transistor: Vmax = 30V, low Logic TRUE
    (Sprague ULN-2803A)
    Logic TRUE: Transistor ON, 1.1 V drop @ 100 mA
    Logic FALSE: Transistor OFF, 0.1 mA leak. @ 50 V.

OUTPUT TIMING:
P: PLC Synchronization Option: Encoder position data
    is latched 50 μs to 3 ms (factory set at 3 ms,
    field-adjustable) after either transition edge of data
    transfer command from PLC (Nonretriggerable during
    timing period).
O: Transparent/Microfreeze Option: Encoder position
    data is continuously updated at full speed. The data
    is frozen (Microfreeze) for 100 +/- 10% μs within
    10 μs of either transition edge of data transfer
    command. Data transfer command is not required if     Microfreeze is not needed.
