Motor description
1.1 Characteristics and technical data
The 1FT5 series was developed for use on a wide range of machine tools.
In conjunction with the SIMODRIVE 611 analog drive converter system, the mo-
tors are admirably suited for, among other things, feed drives on lathes and mill-
ing machines, machining centers, for grinding– and special–purpose machines,
robots, handling equipment and for woodworking.
They can be directly mounted on feed spindles and on gearboxes with toothed
wheels or toothed belts.
!
Warning
The motors are not suitable for direct on–line operation (they cannot be con-
nected to the line supply).
Depending on the shaft height, the 1FT5 series has stall torques from 0,9 to 185
Nm at rated speeds from 1200 to 6000 RPM. They have a high overload capa-
bility over the complete speed range.
The appropriate standards, regulations are directly assigned to the functional
requirements.
The motors are designed for operation on a 600 V DC link and are impressed
with squarewave current. Together with the analog SIMODRIVE 611, they form
a complete drive system.
For DC link voltages which differ from 600 V (max. 700 V), the voltage limiting
characteristic is shifted as described in Chapter ALS/1.1.
Note
If the drive converter is connected to, for example, a 480 V supply, DC link volt-
ages are obtained > 600 V. The following restriction is then obtained: Shaft
heights 36, 48, 63, 71 may only be utilized acc. to the DT=60 K limit values.
