VFD-DD

DELTA VFD-DD AC Drive FEATURES

The Delta VFD DD series elevator door control drive is an intelligent drive with outstanding features that include a modularized design for easy removal and installation of terminal blocks, a power switch designed for safety, and a built-in digital keypad that provides quick operation control. The VFD DD drive offers four door control modes for door opening and closing.

The Delta VFD-DD features a distance control mode that is controlled by an encoder that counts PG pulses to obtain the speed position without sensor. The speed control mode is to control the speed and it needs detection sensors to execute the door open and close action. The multi-step speed control mode of the VFD DD generates a smooth door open-and-close curve using PLC control. The Delta VFD-DD series elevator door control drive provides a complete solution for elevator door control.

DELTA VFD-DD Drive SPECIFICATIONS
The Delta VFD DD automatically determines door width and records data in related elevator parameters. The VFD DD also features:

• Smooth door re-open curve reduces vibration
• DEMO mode
• PM motor A, B, Z, -Z and Delta@@s ECMD-B9160GMS series PM motor
• Supports open collector and voltage output encoder (5~12VDC) for induction motors
• Blockage detection, even if the hardware safety device has failed, VFD-DD can re-open the door according to current detection.
• Precise torque detection, keeps the door open/closed, when the door open/close time exceeds warning, it forces door open

DELTA VFD-DD APPLICATIONS
Delta VFD DD AC motor drives are especially designed for Elevator Door Control applications.
