Servo motors and servo motor controllers: servo drive system

The servo motor controller CMMP-AS is designed for dynamic movements and demanding applications in machine and plant construction. As a highly functional servo drive system, it covers almost all drive applications. It provides an easy and flexible way of adapting modular machine concepts to user-specific requirements.

Stepper motors and stepper motor controllers

The two motor controllers CMMO-ST and CMMS-ST both are a closed-loop servo drive system for stepper motors. As a fully-fledged closed-loop servo system, they use the best possible motor characteristic curve for the highest degree of operational safety and fastest dynamic response. Alternatively, they can be used as a low-cost open-loop system with stepper motors without encoder. The CMMO-ST offers easy system configuration and diagnostics with its integrated web browser.
Stepper motor controller CMMO-ST
- I/O interface (7 freely definable positions via directly allocated I/Os)
- Acceleration with jerk limitation
- Monitoring freely defined positions and torque ranges
- Monitoring different process variables such as torque, speed, position and time
- Positioning mode with optional torque limitation
- Force mode with optional stroke limit
- Speed mode with stroke and force limitation
Stepper motor controller CMMS-ST
- Automatic motor brake
- External braking resistor (optional)
- Jerk-free positioning
- Infinitely variable positioning
- Digital inputs and outputs protected against short circuit, overload and reverse polarity voltages
- Step resolution: full steps up to 4000 steps per revolution
Software tools from Festo for an integrated concept from commissioning to programming to parameterisation, including uniform and easy handling:
- Festo Configuration Tool (FCT)
- Uniform FHPP data profile
Integrated safety functions:
- Safe Torque Off (STO) with category 3, PLd
Compatible with stepper motor EMMS-ST
- Two-phase hybrid technology for long service life and problem-free operation
- Optional encoder for closed-loop function
- Variants with optional motor brake
Degree of protection:
