4 Getting Started
4.1 Overview
With its easy-to-use keypad and X-Press Programming, the IMPULSE•G+/VG+ Series 4 makes it easy to get up
and running quickly. In addition to explaining the keypad and X-Press Programming, this chapter explains how to
navigate the menus and configure the VFD.
4.1.1 Checks Before Powering
After VFD installation and wiring are completed, verify:
•
Correct connections.
•
Correct input power supply (no voltage drop or imbalance, source kVA
500, unless a line reactor is used).
•
No short circuit conditions.
•
No loose screw terminals (check especially for loose wire clippings).
•
Proper load conditions.
4.1.2 Precautions
•
Only start the motor if motor shaft rotation is stopped.
•
Even with small loading, never use a motor whose nameplate amperage exceeds the VFD rated current.
4.2 Using the Keypad
With five 16-character lines available, the keypad display makes it possible to monitor VFD operation, change
parameter settings, and view fault codes. In addition, the parameter description is included on the top line of the
display. The keypad enables you to:
•
Program the various VFD parameters.
•
Monitor the functions of the VFD.
•
Read alpha-numeric fault-diagnostic indications.
•
Operate the VFD using the keypad (local operation).
DANGER
Extreme caution should be used if braking method is set for Decelerate to stop. If deceleration time is too long,
equipment could run into the end stop device, causing damage to equipment or injury to personnel.
WARNING
Because of additional potential hazards when the VFD is operated locally, we advise you to avoid operating it
this way. If the VFD is operated locally, be aware that the crane or hoist will move when the RUN button is
pressed. Contact Magnetek with any questions.
