Installation of two or more servo amplifiers and other equipment
Leave a large clearance between the top of the servo amplifier and the internal surface of the
control box. Due to the power loss of the units it must be ensured that the internal temperature
of the control cabinet does not exceed the ambient temperature of +55 °C allowed for the servo
amplifier. If necessary, the control cabinet will have to be ventilated. In this case, however, the
servo amplifier must not be installed in the flow of coolant of some other operating agent. The
fan(s) in the forced-cooling housing must be installed taking into account the provision of an
optimum supply of cool air.
For details of the heat dissipation of control cabinets and housings please see the
manufacturer’s specifications.
When using heat generating equipment such as the regenerative brake option, install them with
full consideration of heat generation so that the servo amplifier is not affected.
