FST 500 Manual
Thank you for choosing ANYHZ‟s high-performance FST-500 Series. The FST-500 Series is
manufactured with high-quality components and materials and incorporate the latest
microprocessor technology available.
This manual is to be used for the installation, parameter setting, troubleshooting, and daily
maintenance of the AC motor drive. To guarantee safe operation of the equipment, read the following
safety guidelines before connecting power to the AC motor drive. Keep this operating manual at hand
and distribute to all users for reference.
To ensure the safety of operators and equipment, only qualified personnel familiar with AC motor drive
are to do installation, start-up and maintenance Always read this manual thoroughly before using
FST-500 series AC Motor Drive, especially the WARNING, DANGER and CAUTION notes.
Failure to comply may result in personal injury and equipment damage. If you have any questions,
please contact your dealer.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
*******************************************************************************************************************
1. AC input power must be disconnected before any wiring to the AC motor drive is made.
2. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power has
been turned off. To prevent personal injury, please ensure that power has turned off before
opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage
levels.
3. Never reassemble internal components or wiring.
4. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the
input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and W/T3
directly to the AC mains circuit power supply.
5. Ground the FST-500 using the ground terminal. The grounding method must comply with the laws
of the country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram.
6. FST-500 series is used only to control variable speed of 3-phase induction motors, NOT for
1-phase motors or other purpose.
7. FST-500 series shall NOT be used for life support equipment or any life safety situation.

  • Page 2 FST 500 Manual ******************************************************************************************************************! 1. DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive easily damage by high-voltage. 2. There are highly sensitive MOS components on the printed circuit boards. These components are especially sensitive to static electricity. To prevent damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.
