ARIABLE REQUENCY RIVE
• Check the wiring to the motor.
• Check whether there is a short -
circuit between the phases or
an earth fault in a phase.
• Check the variable frequency
drive's ambient air temperature.
Check whether additional clear-
ance or cooling is required.
Make sure that the variable fre-
quency drive is not being over-
loaded.
• Power supply problem.
• Increase deceleration ramp
time P-04.
• Usually occurs if the power is
switched off. If it occurs during
operation, check the power
supply voltage.
• Check the variable frequency
drive's ambient air temperature.
Check whether additional clear-
ance or cooling is required.
• The variable frequency drive will
be switched off if the ambient
air temperature is lower than
14 °F (-10 °C).
• Raise the temperature over
14 °F (-10 °C) in order to start
the variable frequency drive.
• Press the STOP button. The
DC! Variable frequency drive is
ready for an application - spe-
cific configuration.
• External safety shutdown at
digital input 3. The N/C contact
has opened due to some rea-
son.
• Make sure that each individual
variable frequency drive on the
network has a unique address.
• Check the communications
connection between the vari-
able frequency drive and exter-
nal devices.
• Make sure that each individual
variable frequency drive on the
network has a unique address.
• A variable frequency drive
intended for use with a three-
phase power supply has lost
one of its input phases.
