LinMot Installation Guide C1100
6 Power Supply and Grounding
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 protective earth PE.
This includes both LinMot and all
other control system components on 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 drives.)
Power supply connectors must not be connected or disconnected
while DC voltage is present.
Do not disconnect system components
until all LinMot drive 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 drives.
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 the drive.
*
Inside of the C1100 drive the
PWR motor GND
and
PWR signal GND
is connected together and to
the GND of the drive housing. It is recommended that the
PWR motor GND
is NOT grounded at
another place than inside of the drive to reduce circular currents.
