5.1.6 Setting parameters before servo running

To meet onsite application function and performance requirements, you must set parameters by using
the LED panel, PC software, or communication means before servo running. Chapter 6 describes all
parameters, among which some must be set depending on the actual application requirements, such
as the pulse input manner, electronic gear ratio, encoder output frequency division coefficient, and
analog input upper or lower limit, while some must be set depending on the actual commissioning
status, such as the regulator loop parameter affecting system performance, but most parameters use
the default settings.
The following lists only part of mandatory parameters:
Control mode
The control modes include the position, speed, and torque control modes, and any combination of the
three modes. Depending on actual control requirements, set the control mode through P0.03. You
must switch off and re-switch on the main power for the setting of P0.03 to take effect.
Command input
Based on the setting of P0.03, set or enter commands to control the position, speed, or torque of the
servo motor shaft.

In position control mode, the applicable command can be the pulse command (with three input
methods), internal torque limit command, or external analog torque limit command.

In speed control mode, the applicable command can be the internal speed command, external
analog speed command, internal torque limit command, or external analog torque limit command.

In torque mode, the applicable command can be the internal torque command, external analog
torque command, internal speed limit command, or external analog speed limit command.

5.1.7 Servo enabling

You can enable the servo through the external servo enabling terminal SON or P0.04.
When the servo is enabled:

If no alarm is reported, the servo panel displays the default monitoring parameters.

The fan starts running.

In position control mode, if there is no pulse command input, the servo enters the locked state.

In speed control mode, the servo motor runs at the given speed.

In torque control mode, if no torque is applied externally, the servo motor accelerates from the
zero speed to the limited speed. If the external torque is greater than the torque in the internal
torque command, the servo motor remains the state of zero speed output.

If a servo alarm is reported, the servo panel displays ErXX-X and blinks. The servo motor enters
the inertia running state.
