GM215 Stepper Motor Controller - 15 Operating Modes
GM215 Stepper Motor Controller - 15 Operating Modes
The GM215 is a versatile and high-performance stepper motor controller designed to meet the demanding needs of industrial applications. With its 15 operating modes, the GM215 offers unparalleled flexibility and precision in motion control.
The GM215 is a 7A, 80VDC step motor drive with an integrated motion controller. It can be used as a step and direction input motor drive or as a motion control-enabled drive. The operating mode and related functions are set via a 10-position slide switch on the side of the drive. The GM215 features 3 opto-isolated inputs and 3 opto-isolated outputs, with functions determined by the selected operating mode.
Key Features
- Microstepping: The GM215 has a 10 microstep native resolution, dividing each full step angle into 10 equally spaced microsteps for smooth motor operation.
- Step Pulse Multiplier: Synthesizes 10 microstep pulses for every full-step pulse and 5 microstep pulses for half-step pulse, providing smooth motor performance.
- Sub-Microstepping: Divides each input step pulse into 32 sub-microsteps, resulting in motor smoothness equivalent to a 320 microstep drive.
- Morphing: Transitions from sine-cosine motor currents at low speeds to square-wave currents at high speeds, maximizing motor power at higher speeds.
- Mid-Band Resonance Compensation: Uses active second-order damping to suppress motor resonance and stall at medium speeds (300RPM – 900RPM).
- Low Speed Resonance Compensation: Nullifies motor vibrations at speeds below 120 RPM using PROFILE and ADJUST trimpots settings.
- Protection: Protected against motor to ground and motor to motor output short-circuits, reversed power supply polarity, and power supply over-voltage.
- Automatic Standby Current: Reduces motor phase current to 70% of the set value and changes motor switching topology to a low heating recirculating mode after 1 second of inactivity.
Motion Controller Features
- 16-bit MCU, FPGA, Flash ROM, and RS485 Interface: Executes ASCII format commands from an external PC or its own non-volatile memory.
- On-the-Fly Motion Control: Allows changes to acceleration, velocity, and destination while the motor is in motion.
- Multiple Axis Motion: Up to 4 GM215 drives can communicate for coordinated multi-axis motion.
- Run from Stored Program: Executes stored motion programs from non-volatile Flash memory without a computer connection.
- Powerful Command-Set: Includes 'if-then-else' conditional branching, looping, macros, high-speed HOME routines, JOG routines, SPEED control routines, and more.
- Analog Inputs: On-board trimpots for setting acceleration, velocity, and destination, with analog inputs summing to digital value settings for Vernier control.
- General Purpose I/O: Three opto-isolated user-defined inputs and three opto-isolated user-defined outputs.
- RS-485 Interface: Default baud rate of 115,200, with both interfaces available.
- Boot-Loader: Allows user to update GM215 firmware using the built-in boot-loader function.
