and convenient diagnostics a reality
• The modular design allows different product configurations – just as the machine requires
• Optionally available with “Safe Torque Off (STO)” with SIL 3 (EN IEC 62061/EN IEC 61508)
and Performance Level e (EN ISO 13849-1)
• For the greatest possible flexibility available as a complete device or in individual parts
(Power Unit, Control Unit and Safety Unit)
• Can be directly connected without external cooling
• All typical motor control types of modern inverters
• Cyclic and continuous operation of the motor according to common operating modes
• Industry-standard networking opportunities
• High internal functional range
Power unit
