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
•
drive-controlled homing
•
jog
•
drive halt
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
Note: Warning E247 is suppressed if S-0-0259, Positioning
Velocity is cyclically configured.

Interpolation"
E248 Interpolation acceleration = 0
Cause:
The drive internal position command interpolator (profile generator) is
active. It has been given the acceleration = 0. Without acceleration, it can
never reach a given speed.
Note: Input parameter values are converted into a drive internal
format, so an input acceleration word > 0 can, when
converted, result in an acceleration = 0. The parameter values
which, internally, result in an acceleration > 0, can be
calculated using the formulas found in the chapter entitled
"
Drive-internal format of position data "
