Servo Drives

Q: I have used only the position control mode only in the servo drive. Can anyone please explain me about speed/velocity control mode in the servo drive, like for the position control mode we will be giving pulse and direction from the external controller, likewise which thing we need to give for speed control mode?

A: Position control in servo motor mean the motor will travel a defined position with some speed. In Position mode u can control both distance & speed by using controller. Position control is used in applications where more accuracy is needed. In Velocity control mode, the speed is controlled by controlling the voltage (0-10V) through external Pot. It is used in a place where controlling is Analog.

For velocity control, you just need to induce an analog signal on the servo drives terminals, and also a zero input command for some brands. This is a lot easier than the position control mode. It's like treating it as an AC variable frequency drive (VFD), only that the servo motor responds more accurately on different speed commands.
Gozuk synchronous ac servo drive is designed and manufactured, employing the advanced control algorithm based on the market demand, which can realize speed and accurate position digital control. With intelligent power module (IPM) and other latest technology design, simple operation, high reliability, small size, easy to install.
Cover a big range of servo motor which up to 5.5KW.
Gozuk servo drive has mature servo technology and the highest cost performance.servo drive

Servo Drive Features:
Speed range: Steady speed operation of the highest speed up to 5000 RPM, minimum speed 0.1 RMP.
Overload ability: torque can be up to 3 times of the rated load.

High dynamic response: speed loop bandwidth can reach 300 hz, process and load speed change little.

Input/output terminal: light coupling isolation, functional programmable, input terminal can realize servo enabled, alarm clear, torque limit and emergency stop, and other functions, output terminal can be controlled with switch, relay and open collector triode, using Darlington photoelectric coupler for output, can be connected with relay and photoelectric coupler, interfaces are more convenient to use.
 
Analog command control: speed, torque Shared a analog control, can difference or single-ended input, range - 10 v ~ + 10 v.
 
Position control mode: high speed light coupling isolation plus/signal signals, CCW/cw + signal and A/B phase + signal control mode, and employs the difference or single-terminal pulse receive mode, can effectively restrain the interference, optional instruction pulse smooth filtering, make the system in deceleration process smooth operation, increase the pulse signal digital filter and detection way.
 
Resonance inhibition: the servo drive can rise to inhibit resonance effect by adjusting the internal parameters
 
Encoder signal output: encoder signal frequency division and then drive output through line
 
Protection function: over voltage, over current, overload, overspeed and encoder anomaly and other kinds of error detection mechanism, nip in the bud.
