7.6.4.2 Tightening channel configuration with BG5+
By using the power reserves of the servo amplifier LT355 and/or LTS350 and the EC motor EC305 in
the Tightening System 350, the spindle limits of a stationary spindle of size 5 can be expanded as follows:
n
max, motor
= 12,500 rpm (previously 10,000 rpm)
T
max, motor
= 9.5 Nm
An overview of the hardware requirements can be found in section BG5+ with increased performance
(page 47)..
Offline tightening channel configuration with expanded limits is possible if an EC motor (EC305?) is
selected. Additionally, an adjusted system box SB356 with an increased intermediate circuit voltage is
required.
