When standby is activated, drive modulation is stopped, the fan is stopped and the pre-charge circuit is
activated. If the voltage exceeds this level again, the drive has to complete charging before it will
automatically continue operation.
A warning A3A2 DC link undervoltage
occurs:
• When drive is not modulating and the DC link voltage
85% of the undervoltage warning limit.
• The drive is modulating, the DC link voltage
standby limit and the parameter
continues to appear if the DC link voltage is continuously less than the standby
limit until auto restart time elapses.
Note: Control board must be externally powered with 24 VDC to enable warning
in this condition. Else, the control switches off once the DC voltage goes below
hardware limit.

• The DC link voltage
and the parameter
occurs only if the warning continues to appear until auto restart time elapses.
Notes:
• Control board must be externally powered with 24 VDC to enable warning in
this condition. Else, the control switches off once the DC voltage goes below
the hardware limit.
• DC voltage stabilization parameter is available in service level parameters list.
