Where It Fits

• Small conveyors and package handling lines
• Fans and blowers in light duty rooms
• Pumps for water supply and sumps
• Mixers and agitators on small tanks
• Machine tools and simple spindle drives
• Door and gate motion control
• Food and packing equipment in dry areas
• Retrofits where a plate drive drops into an old cutout

Install Guide

• Mount the plate into the panel cutout and fix the screws.
• Keep the heatsink clear so air can flow.
• Set input voltage with the DIP switches before power-up.
• Use a 15 A branch fuse or a listed motor protector.
• Add an external filter when CE limits apply.
• Wire the RS-485 link with terminating resistors at the ends.
• Add an external brake resistor for fast stops.

Setup and Care

• The LED keypad shows faults and settings on the spot.
• Set ramp and stop mode with simple parameters.
• Check the fan and heatsink at each service visit.
• Clear dust from the vents to avoid overheating.
• The plate design allows quick swap without rewiring the panel.

FAQ

• Q: Will this drive run a three-phase motor from a single-phase line?
  • A: Yes. It makes three-phase 0…230 V output from one-phase input.
• Q: Can I control it from a PLC over Modbus?
  • A: Yes. The DSI port speaks Modbus RTU with codes 03, 06, and 16.
• Q: Do I need a separate filter for CE?
  • A: Yes. This build has no internal filter. Add the L type unit.
• Q: From field practice, why does the drive trip on long motor cables?
  • A: Cable length adds capacitance. Keep runs short and fit a filter.
• Q: From field practice, what causes a fast stop to fault?
  • A: The brake resistor is too small or the stop time is too short.
• Q: From field practice, how do I cut RF noise in a panel?
  • A: Use shielded cable. Bond the shield at both ends to PE.
