F58 Mechanical brake
This fault is generated when the acknowledge signal from
the brake is used. If the status of the signal is opposite
from the control signal for a longer period of time than
the delay defined with P1.15.11 Brake Fault Delay a fault
is generated.
Correcting measures:
•
Check the condition and connections of mechanical brake
F59 SystemBus communication
The master drive sends pulses to all follower drives. If
the pulses are missing a system bus communication fault
is generated. The master drive also receives pulses back
from the follower drives (max. four drives) and generates
warnings if pulses are missing.
SystemBus communication is broken between master
and follower.
Correcting measures:
•
Check expander board parameters
•
Check optical fibre
•
Check option board jumpers
F60 Cooling
Protection for the liquid-cooled units. An external sensor is
connected to the drive (DI: Cooling Monitor) to indicate if
cooling liquid is circulating. If the drive is in Stop state only
a warning is issued. In Run state a fault is issued and the
drive makes a coast stop.
Possible cause:
1.
Liquid cooled drive cooling circulation have been failed
Correcting measures:
Check reason for cooling failure from external system.
F61 Speed error
Speed error monitoring function compares the encoder
frequency and the ramp generator output.
This function is used with PMS motors to detect if the
motor is out of synchronization or to disable open loop
function that uses encoder speed for slip compensation. The
slip compensation is disabled regardless of the response
and needs to be re-activated once speed error is detected
(set parameter again or power down the drive).
Possible cause:
1.
Motor speed is not the same as the reference. For
example, motor speed is limited by torque limit
2.
PMS motor has gone off synchronization
3.
Encoder cable is broken
F62 Run disabled
Run Disable warning signal is issued when Run Enable
signal has been removed from the IO.
F63 Emergency stop (not implemented)
Possible cause:
1.
A command has been given from a digital input or the
fieldbus to make an emergency stop
Correcting measures:
•
New run command is accepted after the emergency stop
is reset
F64 Input switch open (not implemented)
Possible cause:
1.
Drive input switch is opened
Correcting measures:
•
Check the main power switch of the drive
F65 Temperature sensor board 2 fault
Temperature protection function is used to measure
temperature and give warning and/or fault when set
limits are exceeded. SPX Advanced application supports
two temperature sensor boards simultaneously. One
can be used for the motor winding and the other for the
motor bearings.
A1 – Temperature limit has been exceeded.
A2 – Sensor not wired or not working.
A3 – Short circuit.
Possible cause:
2.
Temperature limit values set for the temperature board
parameters have been exceeded
Correcting measures:
•
Find the cause of temperature rise
•
Check sensor wiring
F74 Follower fault
When using the normal master follower function this fault
code is given if one or more follower drives trip to fault. This
fault is visible also when fault is in master drive. See also
what other faults may be active in master drive.
Possible cause:
1.
Fault in follower drive or in Master drive
Correcting measures:
•
Identify original fault and problem
