5.1 Applying Power
W A R N I N G
UNINTENDED START
When the drive is connected to AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus command,
an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condi-
tion.
Press [Off] on the LCP before programming parameters.
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
start.
Check that the drive, motor, and any driven equipment are in operational readiness.
N O T I C E
MISSING SIGNAL
If the status line at the bottom of the LCP reads AUTO REMOTE COASTING, or alarm 60, External interlock is shown, it indicates that
the unit is ready to operate but is missing an input signal on, for example, terminal 27.
See 4.8.5 Enabling Motor Operation (Terminal 27) for details.
Procedure
Confirm that the input voltage is balanced within 3%. If not, correct the input voltage imbalance before proceeding. Repeat
this procedure after the voltage correction.
Ensure that any optional equipment wiring matches the installation application.
Ensure that all operator devices are in the OFF position. Panel doors must be closed and covers securely fastened.
Apply power to the unit. Do not start the drive now. For units with a disconnect switch, turn it to the ON position to apply
power to the drive.
5.2 Local Control Panel Operation
5.2.1 Local Control Panel
The local control panel (LCP) is the combined display and keypad on the front of the unit.
LCP functions
Control drive speed in hand-on mode.
Start, stop, and control speed when in local control.
Show operational data, status, warnings, and cautions.
Program drive functions.
Manually reset the drive after a fault when auto reset is inactive.
An optional numeric LCP (NLCP) is also available. The NLCP operates in a manner similar to the LCP. See the product-relevant Pro-
gramming Guide for details on use of the NLCP.
N O T I C E
For commissioning via PC, install the MCT 10 Set-up Software. The software is available for download (basic version) or for order-
ing (advanced version, code number 130B1000). For more information and downloads, see www.danfoss.com.
5.2.2 LCP Layout
The LCP is divided into 4 functional groups:
