Startup MOVIAXIS® startup - Single-motor operation I 5 0 Pxxx controller parameters Pxxx speed control Speed control only parameter set 1. The setting of all parameters important for speed control is supported by the startup functions of the startup manager. Direct alterations to individual controller parameters are reserved for optimization by specialists. Filter accel. precontrol Filter setpoint Speed setpoint Acceleration precontrol Gain accel. precontrol PI-controller + + Torque setpoints Filter speed actual value Speed actual value Incremental encoder/ Resolver Signal processing Figure 92: Basic structure of the speed control loop 06728AEN P-gain speed controller Gain factor of the P-component of the speed controller. Time constant speed controller Integration time constant of the speed controller. The I-component reacts inversely proportionate to the time constant. A large numerical value results in a small I-component, although 0 = no I-component. Filter speed actual value Filter time constant of the actual speed value filter. Speed setpoint filter Speed ramp will be filtered, graduated setpoint entry or interfering impulse at analog output can be smoothed. Filter acceleration precontrol Filter time constant of acceleration precontrol. This constant influences the control response of the speed controller. The differentiator is programmed. P-gain position controller Setting value for the P controller of the position control loop. Amplification acceleration precontrol Amplification factor of acceleration precontrol. This factor improves the control response of the speed controller. PWM frequency Setting the PWM frequency. Operating Instructions – MOVIAXIS® MX Multi-Axis Servo Inverter 139
