1.10.4 Torque setting input signal and motor-generated torque (terminals 3, 5)

Refer to the diagrams shown at below right for the relationship between the torque setting input signal and output
voltage. The torque setting input signal is in proportion to the output torque. However, motor-generated torque
varies with the motor temperature.
0 to ±10VDC

1.10.5 Meter connection method and adjustment (DA1, DA2)

The output speed etc. of the inverter can be displayed by connecting a meter (speed meter) across terminals DA1
(DA2)-5.
The meter can be calibrated from the operation panel or parameter unit. However, if the meter is away from the
inverter, the display value will vary with the wiring distance.
The terminals DA1, DA2 are non-isolated from the control circuit of the inverter. Using a shield cable of within 30m
(98.42feet) for wiring.

REMARKS
Using Pr. 867 "DA1 output filter", you can function the primary delay filter. (Refer to page 195.)
CAUTION
Refer to page 200 for the meter adjustment procedure.
[Example] To provide a 10V DA1-5 (DA2-5) output of 10V at the inverter output speed of 3000r/min, set "3000" (r/
min) in Pr. 55.(factory setting : 1800r/min)
Parameter No.

CAUTION
Note that when wiring is long, a voltage type meter is susceptible to a voltage drop, induction noise, etc.
and may not read correctly.
