CP2000 Series - Sensorless Vector control Drives

Cp 2000 Series Features
Delta's Sensorless Vector Control Drive CP2000 Series has extended the idea of energy saving and uses this principal as the basis of its design. The CP2000 is specifically designed for applications such as air blowers, pumps and HVAC drives with its intelligent PID control providing the greatest efficiency. The Sensorless Vector Control (SVC) offers timely response to load torque increase/decrease which satisfies customer requirements for load changes while enhancing motor performance. A 3-step V/F curve response is used in the variable torque environment to adequately adjust the input voltage and attain the greatest overall performance; this function is especially helpful in pumps and fans applications. It also includes additional functions for operation and protection in variable load environments, such as flying starts, auto-acceleration/deceleration, momentary power loss restarts, auto-tuning, and more. The CP2000 series provides you with the ultimate energy-saving solution for your applications.

VFD-DD Series - Expert Door Control Drives

vdf-dd  Features
The Delta 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. This drive offers four door control modes for door opening and closing. The distance control mode 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 generates a smooth door open-and-close curve using PLC control. The Delta DD series elevator door control drive provides a complete solution for elevator door control.

 Specifications
‧Door width is determined automatically and is recorded in related elevator parameters. 
‧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
