A056 PTC Short Circuit
A056
Description
External PTC resistor short circuit.
Event
Detected the short circuit of the PTC connected to
AIN2
input (R < 10 ohm).
Possible
cause
Short circuit in the PTC.
Incorrect wiring of PTC.
Incorrect setting of
SW1
hardware switch on the control board (see
Installation
Instructions Manual
).
Solution
1. Make sure that the PTC is correctly connected to
AIN2
analog input (see
Installation Instructions Manual
).
2. Make sure that
SW1
hardware switch is correctly set.
A057 Illegal XMDI in MPL
A057
Description
Illegal configuration of XMDI in the
Virtual Digital Outputs (MPL)
Menu.
Event
The drive checked if at least one XMDI input from ES847 or ES870 I/O
option board is available in the VIRTUAL DIGITAL OUTPUTS (MPL) MENU;
The drive checked if
R023
(I/O Board setting) is set to 0 in the
EXPANSION BOARD CONFIGURATION MENU
Possible
cause
Wrong settings.
Solution
Check settings and enter correct settings.
A059 Encoder Fault
A059
Description
Motor speed measure error.
Event
During the encoder tune, a speed error measure occurred with respect to the
estimated speed, although the sign of the measured speed is consistent with the
estimated speed.
Possible
cause
Incorrect parameterization of the encoder concerning the type and number of
pulses/rev.
Voltage removed from one of the two encoders.
Incorrect mounting of the encoders.
Encoder failure.
Solution
1. Check
that
the
encoder
parameters
are
correct
(see
the
ENCODER/FREQUENCY INPUTS MENU).
2. Check that both encoders are properly connected.
3. Check mounting of the encoders.
4. Using an oscilloscope, check that the encoder signals are correct.
