Digital Outputs
• The "Enable pulses" signal is output at digital output 0 (X542:2 and 3).
• The "no fault" signal is output at digital output 1 (X542:5 and 6) (fail safe).
• The "ready to start" signal is output at digital output 8 (X541:2).
• The "LOCAL mode active" signal is output at digital output 9 (X541:3).
• The "Enable pulses" signal is output at digital output 10 (X541:4).
Vdc-max Controller is Active (p1240 = 1)
If the ramp-down time is too short and the permitted DC link voltage is violated
when the drive is decelerated, the ramp-down time is automatically increased so
that the cabinet unit does not have to be shut down with the error "overvoltage in
DC link".
Flying Restart Function is Active (p1200 = 1)
When the drive is switched on, the motor may be rotating:
• due to external influences (water flow for pumps, air from fan drives)
• due to a previous shutdown or power failure, whereby the kinetic energy stored
causes the drive to coast to a standstill slowly.
When the flying restart function is activated, the output frequency of the converter
is varied until the current motor speed is found. The motor then ramps up in
accordance with the settings for the ramp-up generator until the defined setpoint is
reached.

Saving the CompactFlash Card Parameter Settings

After commissioning, you are advised to store the CompactFlash Card data on an
external storage medium (hard disk, data media).
To do so, use a card reader connected to a PC. Ensure that all the files and
directories are stored in the same form as on the CompactFlash card.
If required, you can restore the device status after the drive has been
commissioned by transferring the stored data to the CompactFlash card.
NOTE
You should only remove the CompactFlash card when the system is switched off.
If you remove it while the system is switched on, warning A1100 ("CompactFlash
Card removed") is output.
