4.1.
Power Supply
The BY340 synchronizer accepts both, a 17 … 40 VDC power or a 24 VAC power for supply via terminals 17 and 1. The current consumption depends on the level of the input voltage and some internal conditions; therefore it can vary in a range from 100 … 200 mA
(auxiliary currents taken from the unit for encoder supply not included).
4.2.
Auxiliary Outputs for Encoder Supply
Terminals 2 and 18 provide an auxiliary output with approx. +5.2 VDC (300 mA totally).
Terminals 3 and 19 provide an auxiliary output with approx. +24 VDC (240 mA totally)
4.3.
Impulse Inputs for Incremental Encoders
All input characteristics of the impulse inputs can be set by the parameter menu, for each of the encoders separately. The unit works with quadrature information (A / B, 90°) only. In theory, any of the following encoder characteristics would be applicable:
Symmetric differential signals according to RS422 standard, however
1 V min. as differential voltage.
TTL inputs at a level of 3.0 to 5 V (differential, with inverted signal)
TTL inputs at a level of 3.0 to 5 V (single-ended) *)
HTL signals at a 10 … 30 V level
(alternatively differential A, /A, B, /B, or single-ended A, B only)
Pulses from photocells or proximity switches etc. providing a HTL level (10 … 30 V)
Proximity switches according to NAMUR (2-wire) standard
(may need additional remote resistor)
*) requires special settings of the threshold parameters, see 8.2.9
“Special parameters F08”
For trouble-free angular synchronization it is mandatory to use quadrature encoders with channels A and B or with channels A, /A, and B, /B (90° phase displacement).
Where the impulse level is HTL (10 … 30 V) you can use either single-ended signals (A and B only) or differential signals (A, /A, B, /B).
Where the impulse level is TTL or RS422, it is strictly recommended to use symmetric differential signals (with inverted channels /A and /B). Under industrial environment conditions, single-ended TTL signals may cause serious problems due to insufficient EMC immunity of the signal lines.
All encoder input lines are internally terminated by pull-down resistors (8.5 k Ω ). Where encoders with pure NPN outputs are used, corresponding pull-up resistors must be available inside the encoder or externally to ensure proper function (1 k Ω ... 3.3 k Ω
)
