Item Specifications
Applicable PG model
17-bit, high-resolution ABS encoder manufactured by Tamagawa Seiki Co., Ltd.
TS5667N253/TS5667N650
Allowable revolution speed
TS5667N253: 3,000 r/min
TS5667N650: 1,500 r/min
Power supply for PG
Power is supplied from this option board to PG.
Voltage: 5 V ± 5 %, and current: 70 mA, Typ. (during normal operation)
Allowable wire
length/connection
60 m max.
Wire is short when the voltage drop is high.
The following distribution cables have been prepared, but are arranged separately.
WSC-P06P05-W (5 m)
WSC-P06P10-W (10 m)
WSC-P06P15-W (15 m)
WSC-P06P20-W (20 m)
If a cable required is longer than 20 m, contact us separately.
If the cable is longer than 50 m, the attached terminating resistance must be installed.
Power supply for option
board
The power is supplied from the PCB of the main unit (15 V).
Connect the power harness to CN12 of the main unit.
Pulse frequency dividing
output
5V Line driver A-/B-phase signal output (FA+/-, FB+/-)
Signals obtained by frequency-dividing 17-bit serial data are output. Maximum frequency of
1 MHz.
Note that the frequency dividing rate is "function code E109/E110".
* Calculation example of output frequency
(E109=1000, E110=32767, P28=32768, Serial PG installation axis frequency = 25 Hz)
When a 17-bit serial encoder is used, the pulse resolution (P28) is "17 bits ÷ 4-multiplied =
32768".
Pulse output (Hz) = (E109/E110) x 25 (Hz) x P28
(1000
/32767) x 25(Hz) x 32768 = 25.001 kHz (A-/B-phase output)
