Módulos de inversor duplo KWD

The compact servo drive module KWD contains two independent KW drives in
one enclosure. This represents a low-cost and extremely compact solution for servo
drives with low power ratings.

Benefits:
• Cost-effective and very compact solution for servo drives with small power
• Integrated safety function „STO“
• High efficiency
• More compact machine design

Features:
• Power rating up to 2 x 5 kVA
• Very compact dimensions
• Cooling in cold plate technology
• Integrated safety function „STO“ in PL e according EN ISO 13849-1 and category 4

according EN954-1.
• Accommodates 2 controller cards (KWR03, KW-R03P, KW-R04, KW-R06 or KW-R07).
Controller cards must be ordered separately.
