Key issues

Question 1: What are the three main control modes of SGDH drivers? What signals are given separately?

answer:

Speed control: given by CN1-5 V-REF analog ± 10V;

Position control: given by CN1-7/11 PULS/IGN pulse train;

Torque control: Given and limited by CN1-9 T-REF analog quantity.

Switch modes based on parameter Pn000.1.

Question 2: What are the advantages of absolute value encoders? What wiring and settings should be noted?

answer:

Advantages: Save location during power outage, no need to reset to zero during startup, improving efficiency.

Wiring: * * CN1-21/22 BAT+/BAT – * * backup battery must be connected;

Setting: Pn002.2=0 Enable absolute value, use Fn008 to reset multi cycle data.

Question 3: Which pin corresponds to CN1 for servo enable, overtravel, and alarm reset? What is logic?

answer:

Servo enable/S-ON: CN1-40, low level effective;

Overtravel P-OT/N-OT: CN1-42/43, high level operation prohibited;

Alarm reset/ALM-RST: CN1-44, low level reset.
