Transcription

1 Toothed belt and ball screw actuator EGC/EGC-HD Power unit! Highlights Rigid: optimised aluminium profile for handling very high torques and forces Efficient: optimally sized drive solution using PositioningDrives Reliable: incremental displacement encoder for safety-relevant 2-channel solutions The electric axis EGC comes in numerous variants and has lots of benefits, such as high dynamic response and speed, newly defined rigidity, high load bearing capacity. In short, it is a new range of axes in a mechatronic modular system for both individual and complete system solutions. Versatile The entire EGC range is available as toothed belt and spindle axes. Numerous sizes and slide variants, an optional central lubrication adapter as well as protected guides open up a broad range of applications. Quicker planning The EGC range in the Festo multi-axis modular system offers standardised interfaces for all drives and motor units. Configuration with the PositioningDrives software simplifies the design and prevents costly oversizing. The axis The drive solution Top performer Specially developed profiles with an optimised cross section give the drives maximum rigidity and load capacity. Speed, acceleration and torque resistance set a new benchmark. Heavy-duty variant HD The EGC-HD completes the EGC range with recirculating ball bearing guide. It effectively absorbs lateral forces and torque. As a toothed belt or spindle drive with 2 parallel guides, it is ideal for cantilever systems. The handling system

6 Safety at a glance Sensors and safety solutions Reliable thanks to optional sensing Inductive proximity sensor SIES-8 M Flush mounting of up to 2 sensors in the profile slot no protruding edges outside of the actuator cross section Output status display: 2 yellow LEDs for improved visibility, regardless of the direction of approach Features SIES-8M As normally open/normally closed contact with switching output PNP and NPN Switching distance 1.5 mm Repetition accuracy ±50 µm (radial) Max. 10 m cable length Displacement encoder for monitoring the linear actuator The slide position cannot be monitored directly by the encoder in the motor for safety critical applications since if there is a fault in the motor encoder, a secondary system is required to determine if the actuator slide is moving. Incremental displacement encoder for position detection Enhanced absolute accuracy due to linear displacement encoder Detection of all drive train elasticity System-intrinsic inaccuracies can be optimally adjusted by the motor controller Minimum resolution: 2.5 µm at a maximum 4 m/s Suitable for safety-oriented applications (second channel) However, with an external linear displacement encoder mounted directly on the actuator, the axis slide position can be monitored and the information fed back to a safety system. Functional safety The Machinery Directive 2006/42/EC requires numerous safety functions as protective measures for sufficient risk reduction according to the DIN EN and EN standards. Servo drive CMM The safety function STO is integrated as standard in all motor controllers in the CMM... series. This allows easy implementation of the emergency stop requirements with safe stop SS1 up to category 3, PLd. For higher requirements, the series CMMP-AS- -M3 provides optional safety modules for safety functions up to category 4, PLe. 6 Implementing these safety functions in a practical manner requires different components that can easily be integrated into an overall concept. Safety system CMGA Safely monitors command input devices, safety sensors, safety switches, encoders and measuring systems and processes their input signals in order to guarantee the safe status of a handling unit through appropriate, safetyoriented reactions.
