Approval
ᜢ ᜫ
01) It calibrates the multi-turn count by comparing single-turn data before/after power off without counting multi-
turn count when power off. Correct multi-torn count cannot be obtained if a rotating operation exceeding ± 90°
is performed at the rotation position when power off.
02) Outputs when multi-turn count is out of counting range (0 to 8191 revolution).
03) Based on cable length: 2 m, I sink = 32 mA
04) If the single-turn data reset signal is applied, the single-turn data will be initialized to 0.
05) If the multi-turn count reset signal is applied, the multi-turn count will be initialized to 0.
06) For parallel model Select resolution to satisfy Max. allowable revolution ≥ Max. response revolution
