Motor Control

We offer several versions of the Elliptec Module. All modules share the same mechanics but differ in their factory-loaded software and in the way the control signals C1, C2 are used.

Elliptec Module R40N type „DC-Motor “
A control motor speed using a digital (Normal Mode) or analog (Enhanced Mode) control signal.

In Normal Mode, the Elliptec Module R40N operates at full speed and torque. Control Signal C1 selects the direction of motion. Control Signal C2 starts and stops the drive.

In Enhanced Mode, the drive speed is variable. Control Signal C2 starts and stops the drive. Control Signal C1 sets the drive speed and direction as follows:
- clockwise motion: 1V (no speed)… 0V (full speed)
- counter clockwise motion: 2V(no speed)…3V (full speed)

For C1 voltages exceeding 3V or 0V, the motor speed remains maximal.

Elliptec Module R40S type „stepper motor“
A control stepping motion using a Step-and-Direction control signal comparable to standard stepper motor control schemes. Each step is executed with maximal speed and torque. The step size is given by the resolution of the internal position sensor (Normal Mode) but can be variable and smaller (Enhanced Mode).

In Normal Mode, the Elliptec Module R40S operates as a stepper motor with the fixed step size of the internal position sensor. Each step is executed at full speed and torque. Control signal C1 selects the direction of motion. Each pulse (>10ms) on C2 executes one single step in that direction. The internal microcontroller buffers the pulses in case that the motor is stepping slower than the pulse sequence. Steps are thus not lost even if the motor runs slowly due to a high motor load.

Enhanced Mode allows the drive to override the internal position sensor and execute shorter steps. Control signal C1 selects the direction of motion. Each pulse (10ms) resets it. The microcontroller buffers the pulse sequence on C2 so that no steps are lost due to load-related slow motor response.
