12 Planetary Gear / otor Brake / Encoder / CE / Ordering Code Optional: PLE Low-acklash Planetary Gear The use of a gear ox is recommended if a high resolution of the drive system or a low output speed is required. The overall unit motor with planetary reducing gear has a higher output torque and reduced mass inertia. -stage, -stage or -stage gear with reduction ratios from : to : High driving torque up to Nm, depend. on motor size and reduction ratio High torsional stiffness Low torsional acklash: < to < angular minutes depend. on gear size and reduction ratio High permissile axial and radial shaft loads Low running noise Temperature range to + C Lifetime grease lurication Drawings, dimensions and mechanical characteristics see page /. Optional: KEB otor Brake For vertically mounted positioning systems, stepper motors with rake are recommended. The permanent magnet rake is activated when the rake is de-energized. The permanent magnet pulls a rotor disk in the axial direction towards the contact surface, thus creating a friction-tight junction, free of rotatory acklash. When the current is activated, the force acting on the rotor disk is suppressed. The contact surfaces are separated without a residual friction moment y means of a riveted spring. Supply voltage V DC Electrical connection y means of a metrical cale gland. Current consumption KEB : approx. ma KEB : approx. ma KEB : approx. ma For drawings and dimensions, please refer to pages and. Optional: E, H or H Encoder ZSH stepper motors with mounted encoder are specially adapted for applications with variale speed drives or to monitor the drive. Short-circuit-proof RS line driver E Encoder Supply voltage: to V DC Resolution: lines Output signals: Channels A and B, A and B The A and B (A and B) signals are phase-shifted. H / H Encoder Supply voltage: V ± % DC Resolution: / lines Output signals: Channels A and B, A and B The A and B (A and B) signals are phase-shifted. und reference pulses For drawings and dimensions, please refer to pages and. EU-Directives and CE marking When installed appropriately, ZSH stepper motors meet the requirements of the EC and Low Voltage Directives. ZSH stepper motors are marked CE and comply with EN - European standard. When wired correctly, ZSH stepper motors meet the requirements of the EC Directive. Information concerning the connection of the motor cale to the control unit or the power stage is given in the corresponding manuals. According to the achine Directive, the stepper motor is only a part of a machine. The machine manufacturer must take appropriate measures to ensure that the entire system meets the requirements of the applicale EU- Directives.
