Installation and Commissioning

Installation and CommissioningExternal AxesWhen designing the drive system following has to be checked:• Max motor current, in order not to demagnetize the motor.• Max/rated current from drive inverter.• Max/rated current from drive unit (sum of all inverters on same drive unit)• Max/rated current from dc-link• Max/rated power for bleeder• Max/rated power from transformerNote: If the system contains axes with no stand by state (the axes will continue to becontrolled while the brakes are activated for the robot), the max allowed power consumptionof these axes are 0.5 kW.Note:For safety reasons, the power supply to the external motor must be switched offwhen the robot is in the MOTORS OFF mode.Drive system configuration with one external axis at Drive System 1 in S4C robot cabinetand five to six axes at Drive System 2 installed in external cabinet.DRIVE SYSTEM 1DRIVE SYSTEM 2Drive System 1serial communicationDrive System 2serialcommunicationExternalaxis drivesystem 1(1 axis)Unit number0 3 2 1RobotaxesUnit number0* 3* 2* 1*Externalaxes drivesystem 2(5-6 axes)Transformer 1Transformer 2Figure 60 Drive systems with external cabinet.Product Manual IRB 1400 101
