Key issues

Question 1: What are the three main operating modes (Pn/Fn/Un) of the ∑ – V servo responsible for, and which functions are most commonly used on site?

answer:

Pn (parameters): Core settings such as control mode, electronic gear, gain, protection, etc.

Fn (Function): During on-site debugging, JOG jog, origin search, parameter initialization, and automatic tuning are the most commonly used.

Un (monitoring): Real time monitoring of speed, torque, position deviation, and I/O status for troubleshooting.

Question 2: What is the function of the CN8 interface for the safety feature of SGDV drivers? What must be done when not using security features?

answer:

CN8 is used for HWBB hard wired base block, achieving the highest level of safety cut-off such as emergency stop and safety door.

When the safety function is not in use, the factory provided short-circuit plug must be installed, otherwise the drive cannot turn on Servo ON.

Question 3: Why can’t the ∑ – V servo be operated immediately after power failure? What is the function of CHARGE light?

answer:

The large capacity capacitors inside the driver may retain high voltage, posing a risk of electric shock when in direct contact.

If the CHARGE light is on, it indicates that there is still electricity inside. It is necessary to wait for the light to completely turn off (usually for more than 5 minutes) before wiring or disassembly can be carried out.
