Instruction manual 91/121 V6.3
•
LOW: The resolver’s signal is low. Rotate the trimmer next to the X14 connector in the hourly direction.
•
OK: The resolver’s signal is correct.
•
HIGH: The resolver’s signal is high. Rotate the trimmer next to the X14 connector in the anticlockwise direction.
SinCos signal A and B
Indicates the status of the voltage signal coming from SinCos or EnDat connected to X14 pin 3-4-6-7. The available statuses are:
•
LOW: The transducer signal is low. The cable or wires could be interrupted or short-circuited.
•
OK: The transducer signal is correct.
•
HIGH: The transducer signal is high. The transducer may not be compatible or the connections are wrong.
SinCos signal C and D
Indicates the state of the voltage signal coming from SinCos connected to X14 pin 19-20-21-22. The available statuses are:
•
LOW: The transducer signal is low. The cable or wires could be interrupted or short-circuited.
•
OK: The transducer signal is correct.
•
HIGH: The transducer signal is high. The transducer may not be compatible or the connections are wrong.
Man Offset Calc
This menu only appears with the optional boards for SinCos (01/325) or for EnDat (01/327).
With the drive disabled (Led RUN off) you can change the parameter in ENABLED, to activate the calibration function automatically
the offset of the incremental sinusoidal signal of the encoder.
For the calibration procedure, see the explanation of paragraph ”5.5.5“ on page 61.
Serial comm. status
Indicates the status of the serial connection of the EnDat encoder connected to X14 pin 9-10-11-12. The available statuses are:
•
FAULT: serial communication problem with the encoder. Check the status of the wires and connections on X14 pin 9-10-11-
12, the shielding of the cable, the presence of noise sources near of the cable.
•
OK: The signal from the transducer is correct.
Internal alarm status
Indicates the state of the internal alarms of the EnDat encoder connected to X14. The available statuses are:
•
FAULT: the encoder reports an internal failure. Replace the encoder with a working one.
•
OK: the encoder has no faults.
Compatible encoder
Whether the EnDat encoder connected to X14 is compatible with the 01/327 card. The available statuses are:
•
NO: the encoder isn't compatible. Check the 5.5.3 page paragraph 58 with the list of compatible encoders.
•
YES: the encoder is compatible.
Advanced Setup
Menu group for advanced configurations. Normally these parameters do not serve for normal use of the drive and the variation of
these can cause adjustment instability or make the motor speed control characteristics worse. Before changing the parameters of this
menu group it is necessary to know the product in depth or contact the ALTER technical office for advice and possible clarifications.
Alter Menu
Password protected menu for internal use. It is not recommended to try to access this menu because the modification of these para-
meters can cause internal damage of the drive with consequent need of repair.
Speed Ramp
Menu group for adjusting the parameters of the speed ramp that can be inserted with the external command "REN" (see paragraph
”Connector X12“ on page 19). In the following drawing you can see how the ramp block is structured.
