E225 Motor overload
The maximum possible motor current is reduced in order to protect the
motor from being destroyed.
If a current flows in the that is greater than 2.2 times the motor current at
standstill S-0-0111, the maximum possible motor current (S-0-0109,
Motor peak current) is reduced. With 4-fold motor current at standstill,
the reduction starts after 400 ms. With 5-fold current it starts earlier, and
with 3-fold current later.
The E225 Motor overload warning is issued when the motor peak
current is reduced by the limitation.
The reduction also has an effect on the P-0-4045, Active permanent
current.

E226 Undervoltage in power section
If bit 5 of the P-0-0118, Power off on error parameter has been set, an
undervoltage condition will be handled as a nonfatal warning. The drive
issues this warning if the drive enabling signal is present and the DC bus
voltage message disappears.
Cause:
Power supply unit is switched off or mains failure occurs while the drive
enabling signal is set.
Remedy:
Switch off the drive enabling signal before you switch off the power
supply unit.
E247 Interpolation velocity = 0
The drive-internal position command value interpolator is active if
•
the "drive-internal interpolation" mode
•
the "relative drive-internal interpolation" mode
•
drive-controlled homing
•
Jog
•
drive halt
•
Process block mode
is active
The E247 warning is issued if the employed velocity specification is 0.
Possible velocity specifications are:
• S-0-0259, Positioning velocity
• S-0-0041, Homing velocity
• S-0-0091, Bipolar velocity limit value
• P-0-4030, Jog velocity
• P-0-4007, Process block velocity
