Introduction
MAN-WHTWIG (Ver. 1.604)
12
The Whistle and Tweeter are available in two models:
•
The Standard models are basic servo drives which operate in current, velocity and
position modes include PT & PVT. They operate simultaneously via RS-232 and CAN DS
301, DS 305, DS 402 communications and feature a third-generation programming
environment.
•
The Advanced models include all the motion capabilities and communication options
included in the Standard model, as well as advanced positioning capabilities-ECAM,
Follower and Dual Loop-and increased program size.
The two models operate with both RS-232 and CAN communication.
