1.5.4 Connecting the Power Infeed
Set controller enabling switch on command value box to OFF and set
speed command value to 0 volts.
The power is applied by shunting the ON and OFF contacts on terminals
strip X15. Do this by using a ten-pin terminal block with two switches, i.e.,
a N/O contact between terminals 1 and 2, and an N/C between 3 and 4.
Attach the terminal to X15.
The power must not be disconnected with the N/C contact
when the motor is rotating as the motor could coast
uncontrollably. Switch the control input E-stop (X2/23) to 0. Fit
N/C contact between X2/18 and X2/23 (see Figure 4, section
1.3). The motor is then braked to a standstill before the main
contactor is disengaged!
Check the messages on the control panel:
• the green READY LED must come on and
• the message NO RF (no controller enabling signal) appears on the
display.
Press the "up" arrow key until the DC bus voltage (UD) appears. A
voltage of between 480 and 550 V must be indicated.
1.5.5 Initial Start-Up
Switch on controller enabling signal on command value box. Apply a
small command value. The speed of the drive must follow the command
value input.
With a fault, the drive can "chatter" uncontrollably. Disconnect
the controller enabling signal immediately. If the motor rotates
in an uncoordinated way, check that the phasing of the motor
power connections is correct. If the motor rotates at low speed
only without following the command value, check the feedback
connections.
The drive must reach the speed specified in parameter MAX RPM (A01)
when the command value voltage programmed in paramter CMD VOLT
(A02) is applied.
