E34 Current Detection 1 (Level 1)
E35 Current Detection 1 (Time)

Refer to the description of E37.
E36 Speed Detection 2 (FDT) (Detection level) (refer to E31)

Refer to the description of E31.
E37 Current Detection 2 (Level 2)
Function code E34, E35 and E37 specify current detection level and timer.
- Data setting range (E34 and E37): Current value of 1 to 200% of the inverter rated current in
units of amperes. (0.00: disable)
- Data setting range (E35): 0.01 to 600.00 (s)
E34, E35 are set for over torque current detection (Ot) when L98 (bit 0) is set to 1.

For details, refer to the description of function codes L98 (bit 0).

Current detection
Setting any of E20 to E24 and E27 data to "37" or "38" assigns the output signal "Current detected 1,
ID " or "Current detected 2, ID2 " to the general-purpose programmable output terminals respectively.
The ID or ID2 comes ON when the output current of the inverter has exceeded the level specified
(by E34 for ID or by E37 for ID2 ) and the output current continues longer than the period specified
by E35 (Current detection time). It turns OFF when the output current drops below 90% of the rated
operation level. (minimum width of the output signal: 100 ms).

E39 RRD Detection Level
This parameter sets the detection level of the recommended running direction at battery operation.
-
Data setting range: 0 to 100 (%) (operation level)
■
Judgment of recommended running direction
When inverter is controlling a motor with low efficiency (like worm gear motor), load variation
between car and counterweight might not be detected. In this case, please set this level to detect
RRD correctly.
Please follow the procedure below:
1.
With balanced load, run the elevator in up direction and observe the torque command
at constant speed.
2. With same condition, run the elevator in down direction and observe the torque
command at constant speed.
3. Please set E39 to the larger torque command observed among step 1 and 2.
