650S AC Drive
Introduction
The 650S Series AC Drive provides simple, compact, and low-cost sensorless speed control for 3-phase PMAC motors with
sinusoidal Back EMF.
This manual describes the low-power end of the 650S product range for the following motor power ratings:
Nominal Input Voltage Phase
Drive Power
Frame 1 230V
1
0.25 – 0.75kW
0.3 - 1.0 Hp
Frame 2 230V
1
1.1 – 1.5kW
1.5 - 2.0 Hp
Frame 2 400V
3
0.37 – 2.2kW
0.5 - 3.0 Hp
Frame 3 400V
3
3.0 – 7.5kW
4.0 - 10.0 Hp
The drive features:
•
Local or Remote mode operation
•
SELV control terminals (Safe Extra Low Volts)
•
Intelligent monitoring strategy to avoid nuisance tripping
•
In-built protection of the unit against overloads, excessive voltages, phase-to-phase and phase-to-earth short circuits
•
An internal RFI filter is fitted as standard
•
An internal dynamic brake switch for connection to an external resistor (400V units only)
•
Quiet operation
•
Controlling the unit locally using the 6511 Keypad gives access to parameters, diagnostic messages, trip settings and full
application programming.
Note:
Do not attempt to control motors whose rated current is less than 50% of the drive rated current. Poor motor control
may occur if you do.
