If an error occurs during these initialization procedures, then error F223
Error during initialisation of the parking axis is generated. To specify
the error more precisely, it is necessary to activate the transition
command phase 3 to 4.
Recovery:
1. bring drive into parametrization mode
2. the switching command phase 3 to 4 must be started
3. and the switching command error must be cleared

F224 Maximum braking time exceeded
Cause:
The decel time of the drive is monitored when the drive enable removed
and given an error reaction with velocity-controlled standstill of the drive.
If maximum decel time is exceeded (Parameter P-0-0126, Maximum
braking time), then the drive is brought to a torque-free standstill and
error F224 Maximum braking time exceeded is generated.
Remedy:
1. extend P-0-0126, Maximum braking time
2. increase brake ramp of error reaction
P-0-1203, P-0-1201 or P-0-1211 and P-0-1213.
3. reduce external moment of inertia
4. increase torque limit value

F226 Undervoltage in power section
The level of the DC bus voltage is monitored by the drive controller. If the
DC bus voltage falls below a minimal threshold, the drive independently
shuts down according to the set error reaction.
Cause:
1. The power source has been interrupted without first switching off
the drive enable (RF).
2. Disturbance in the power supply
Remedy:
For 1. Check the logic regarding the activation of the drive within the
connected control.
For 2. Check the power supply.
The error can be cleared by removing the drive enable signal.
