Control Modes for Drives

With MOONS' advanced stepper drive technology, each stepper motor can be operated under various control modes as position control, velocity control or torque control. MOONS' stepper drive accepts all types of control signals including digital, analog and Industrial network communications. Built-in controller Q drive supports stand alone operation for single axis motion by stored sofiscated program execution.

◇ Pulse Control

Pulse control is a traditional way to command a stepper motor in position and velocity control. The length of rotation is proportional to the number of pulses as well as the speed is proportional to the pulse frequency. Control Modes for Drives-Pulse Control Three most popular pulse control digital signal types are Pulse & Direction, CW/CCW Pulse and A/B Quadrature. Pulse & Direction When the Pulse input is turned ON while the DIR input is ON, the motor will rotate by one step in one direction. When the Pulse input is turned ON while the DIR input is OFF, the motor will rotate by one step the other direction. *Direction definition of DIR input can be configured via MOONS' software. The chart below shows motor configured as while the DIR input is ON, the motor will rotate by CW direction. Control Modes for Drives- Pulse & Direction CW/CCW Pulse When the X1 input is turned ON, the motor will rotate by one step in One direction. When the X2 input is turned ON, the motor will rotate by one step in the other direction. *Direction definition can be configured via MOONS' software. The chart below shows motor configured as while the X1 input is ON, the motor will rotate by one step in CW direction. Control Modes for Drives- CW/CCW Pulse A & B Quadrature The motor will move according to signals that are fed to the drive from a two channel incremental master encoder. Direction definition can be configured via MOONS' software. Direction is determined via which channel leads the other. The chart below shows motor configured as while X1 Leads X2, the motor will rotate by CW direction. Control Modes for Drives- A & B Quadrature

◇ Analog Control

MOONS' stepper drive has the ability to accept analog signal for position and analog control, can also use analog signal for torque control. Control Modes for Drives- Analog Control

◇ Field Bus Control

MOONS' stepper drive supports all popular Industrial network communications including RS-485, Modbus, CAN, Ethernet and EtherCAT. Control Modes for Drives- Field Bus Control

◇ Stand Alone Operation

MOONS' Built-in Controller Q drive supports stand alone operation for single axis motion by stored sofiscated program execution. It has the ability to run up to 744 lines of stored Q program in non-volatile memory. Q programs are created using the Q Programmer software, which provides multi-tasking, math calculations using analog and digital parameters, conditional processing, data register manipulation, and more features in a robust yet simple text-based programming language.
