Instead of two separated power supplies it may be possible to use only one power supply if there is no
need to control the signal power supply (logical devices of the controller) and the power supply of the
powerstage for the motors independently (see safety rules of the application).
In order to assure a safe and error free operation, and to avoid severe damage to
system components, all system components must be well grounded to either a
single earth or utility ground. This includes both LinMot and all other control system
components to the same ground bus.
Each system component should be tied directly to the ground bus (star pattern), rather
than daisy chaining from component to component. (LinMot motors are properly
grounded through their power cables when connected to LinMot controllers.)
Power supply connectors must not be connected or disconnected while DC
voltage is present. Do not disconnect system components until all LinMot controller
LED's have turned off. (Capacitors in the power supply may not fully discharge for
several minutes after input voltage been disconnected).Failure to observe these
precautions may result in severe damage to electronic components in LinMot motors
and/or controllers.
Do not switch Power Supply DC Voltage. All power supply switching and E-Stop
breaks should be done to the AC supply voltage of the power supply. Failure to observe
these precautions may result in severe damage to controller.
