PuOcC Protection
User-defined
Over-current
Phase C
threshold, this software
protection can be
considered unfunctional,
as long as the hardware
protection is available.
PuUv Protection
User-defined
Under-voltage
Indicates that the DC bus
voltage is measured below
the user-defined threshold
(0x2006:1 Protection
Undervoltage setpoint).
As the threshold is user-defined, please first
check the object 0x2006:1 Undervoltage
setpoint.
Then please refer to the remedy for under-
voltage.
PuOv Protection
User-defined
Over-voltage
Indicates that the DC bus
voltage is measured
exceeding the user-
defined threshold
(0x2006:2 Protection
Overvoltage setpoint).
As the threshold is user-defined, please first
check the object 0x2006:2 Overvoltage
setpoint.
Then please refer to the remedy for over-
voltage.
Hardware Protection Faults Errors triggered by
hardware built-in
protection logic.
PhUdef Protection
Hardware
Undefined
Indicates that the
hardware protection
reports an error not
defined in the CiA 402
standard.
Please note down the information regarding
the occurence of the error and reach
Synapticon technical support for further
investigation.
PhFault Protection
Hardware Fault
A generic hardware fault
was detected.
Please note down the information regarding
the occurence of the error and reach
Synapticon technical support for further
investigation.
PhWtdg Protection
Hardware
Watchdog
The watchdog is a service
that checks periodically
with a timer to guarantee
that the drive control logic
is working in the proper
frequency. This error
indicates that the
watchdog tick is not
received on time by the
hardware protection, thus
the drive is not working
properly.
Please note down the information regarding
the occurence of the error and reach
Synapticon technical support for further
investigation.
PhDeadTA Protection
Hardware
Deadtime
Phase A
Deadtime is a common
protection strategy in
PWM control for avoiding
a bridge shoot-through, a
short-circuit accident
Please note down the information regarding
the occurence of the error and reach
Synapticon technical support for further
investigation.
