7. Use the torque control function block, what is going on?
1. Whether the torque given value is reasonable: a given torque value is 10 times different from the actual value; such as a torque given value 100, 10.0% torque received by the actual servo. 2. The speed limit in the torque mode is reasonable 3. Mode switching function block. BDONE signal must have logic control。

8. What kind of output signal does the LS500 series Frequency converter support?
1, 1 high-speed pulse output terminal (optional as an open circuit electrode), support 0 to 100 kHz square wave signal output; 2, 1 DO terminal, output voltage range: 0-24V, output current range 0-50mA; 3, 1 relay output terminal, contact drive capacity 250Vac, 3a, cosø = 0.4 30VDC, 1A; 4, 1 AO terminal, support 0 to 20 mA current output or 0 to 10V voltage output.

9. Frequency converter DO Output Function No. 15 function (running ready), what is the output?
Frequency converter Output effective signals after power-on and in failure.

10. How does the DO terminal of the LS300 series Frequency converter use external power supply how to connect?
Use external power toWhen the DO is powered, the J7 jumper is used to short the 24V, EXT; when power is powered with the internal power supply, the J7 jumper is used to short In, 24V; DO1 corresponds to COM.

11. LS500 series Frequency converter Define DI terminal function as emergency parking, can this emergency parking time can be set? Can parking speed adjustment?
When the system is in an emergency, Frequency converter followsF8-55 terminal emergency stop deceleration time deceleration, V / F mode emergency stop deceleration time is reduced according to minimum unit time. The input terminal does not have to continue in a closed state, even if the time in the closed state is only an instant, it will stop. Unlike the general deceleration time, disconnect the emergency parking input terminal after the emergency stop deceleration time, if the Frequency converter terminal run signal is still closed, Frequency converter will not start, need to be broken Enter the terminal run command again after the running terminal, Frequency converter will then restart. However, the speed of emergency parking is not adjustable, and the speed will vary depending on the load type.
