Equipping the system boxes
A tightening channel consists of the following
components:
• Stationary tightening spindle or ErgoSpin
hand-held nutrunner with connection cable
• Controller
• Servo amplifier
If the appropriate control and servo
components are installed, both stationary
tightening spindles and ErgoSpin hand-held
nutrunners can be connected to and
operated on the SB356 system box. Mixed
operation of stationary tightening spindles
and ErgoSpin hand-held nutrunners on an
SB356 is possible at any time.
The maximum permissible peak current for up
to six tightening channels in the system box is
140 ampere. This is why you may only install
components with a power consumption that
does not exceed a total of 140 ampere.
Total power consumption (tightening
sp ErgoSpin)
≤
140 A
Table 5 shows an overview of the power
consumption of tightening spindles and
ErgoSpin hand-held nutrunners.
