● X70 for the optional modules (OM1, OM2)
See index entry "X70 → External 24V supply".
When dimensioning the power supply unit, take all power consumptions at
X18 and X70 into account.
Observe the reduced tolerance of the 24V voltage when operating motor
holding brakes. To supply the motor holding brakes, use separate power sup‐
ply units, if necessary, or such power supply units with adjustable output volt‐
age.
Notes on Installation
● Fusing (recommended fusing for operation under rated conditions)
– X18.1: 8 A
– X18.2: 2 A
– X18.3: 4.5 A
● Requirements on the connection to the 24V supply
– Maximum cable length: 10 m
– Twist wires
– Observe specified minimum cross section
– Maximum allowed inductance: 100 µH (2 twisted single strands, 25
m long)
● Control voltage (0 V)
Ground the control voltage (0 V) as near as possible to the drive control‐
ler so that the lowest possible impedance to the ground connection of
the drive controller is ensured.
8.3 DC Bus Load
8.3.1 General Information
The DC bus is loaded by the outputs of the inverter. With the given data, al‐
lowed performance profiles have to be determined for a cycle. The sum of
output loads mustn't exceed the given limit values. Balancing processes by
simultaneous infeeding and regenerative processes of the individual axes are
taken into account in the data.
