 Product Info:

1. Torque Control

• Ramp (adjustable), limiting the increase of torque. Optimal adjustment adapts the capabilities of the drive, thus eliminating overshoot.

2. Velocity Control

• Filter for command value (adjustable)
• Acceleration profile: trapezoidal or s-curve (adjustable)
• Velocity-torque control combination by second command value

3. Position Control

• Homing procedure using limit switch or limit switch in combination with index of encoder or current rise due to driving to mechanical limits. An offset can be set for zero position.
• Brake signal is generated after delay and remaining in a position window (adjustable).
• 16 positions being selected via 4 digital input signals (model IMD: 8 positions); positioning is initiated by digital input signal
• Set command position as actual position by digital input signal
• Output signals: positioning completed, homing active, position distance or time required to travel to position
• Position definition in absolute, relative and relative to actual position (shift to absolute positioning is always available)
• Changing position while travelling: ignore / subsequent / immediate
• Speed at destination position can deviate from zero (smoothen moving from point to point)
• Torque increment to compensate stick slip effect (adjustable) enhances dynamics for positioning

4. Synchronization

• Velocity
• Position (for enhanced dynamic simultaneous feedback of velocity and position)
• Combination of positioning and synchronization (i.e. cutting of constant flowing material)

5. Stepper motor control interface: command by pulse and direction signals

6. Sinusoidal commutation capabilities with encoder and hall sensors as feedback devices

Auxiliary 24 VDC (0,5A) Logic Supply Voltage for all models is required.

Operation surface

• Running under MS Windows®
• Simplified set up with automatic parameter setting and motor phase recognition
• Scope and generator integrated for fine tuning
• Handling of parameter files
• Creating of customized programs (option)

Model IMD-310 - no filter, max. 8 positions, one monitor interface
