*Inside of the B1100 controller the PWR motor GND and PWR signal GND is connected together and to
the GND of the controller housing. It is recommended that the PWR motor GND is NOT grounded at
another place than inside of the controller to avoid circular currents.
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 controllers LEDs have
turned off. (Capacitors in the power supply may not fully discharge for several minutes
after input voltage has 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.
