A056 PTC Short Circuit
A056 Description External PTC resistor short circuit.
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
Solution
1. Make sure that the PTC is correctly connected to AIN2 analog input (see
Installation Guide).
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
optional 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
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
estimate
d 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.
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.
