10 to 3000
0, 1 to 3600 s (times out at approx. 24 hours if 0 is specified)
1 Hz to 1 kHz (when the synchronization source for the cycle-by-cycle measurement is U or I)
0.1 Hz to 1 kHz (when the synchronization source for the cycle-by-cycle measurement is EXT
CLK)
U, I (direct input), P, Speed, and Torque
Add (0.3 + 2×f)% of reading + (0.05 + 0.05×f)% of range to the accuracy when the line filter
is OFF in normal measurement (with the line filter turned ON)
I (external current sensor input)
Add (100 + 100×f) µV to the accuracy above
Freq
Add (0.3 + 2×f) % of reading to the accuracy in normal measurement
The variable f is the frequency of the synchronization source for the cycle-by-cycle
measurement in unit of kHz.
