A082 Encoder Configuration
A082 Description
Functions programmed for MDI6 and MDI7, or Encoder B selected and encoder board
not detected.
Event
• Encoder A has been selected for speed measure or as a reference source, but
different digital command functions are programmed for terminals MDI6 and MDI7.
• Encoder B has been selected for the speed measure or as a reference source, but
the control board did not detect any optional encoder board.
Possible
cause
• Incorrect setting of the use of the encoders in parameter C189.
• Incorrect programming of digital input functions.
• Optional board for Encoder B is not fitted, has been improperly mounted or is faulty.
Possible connector failure.
Solution
1. Check and adjust the value set in C189 (see the ENCODER/FREQUENCY INPUTS
MENU).
2. Check and adjust the control function programming for digital inputs MDI6 and MDI7
(see the DIGITAL INPUTS MENU).
3. Check if optional encoder board is fitted and properly mounted.
A083, A084, A085 External Alarm
A084 (EXT2)
Description
A084: External alarm 2
Event
The External Alarm (1, 2, 3) functionality has been programmed, but the relevant digital
input is disabled (see the DIGITAL INPUTS MENU
). If multiple digital command
sources are programmed, alarms A083-A085
trip if one of the terminals in the active
sources is disabled (see the CONTROL METHOD MENU).
Possible
cause
The cause for the alarm trip does not depend on the drive; check for the reason why the
contact connected to terminal MDIx where
the External Alarm function is programmed
opens.
A087 ±15V Loss
A087 Description Loss of ±15V.
• The voltage level of ±15V is inadequate.
• Possible failure of the control board or other circuits in the Penta Drive.
Solution
1. Reset the alarm: send a RESET command.
2. If the alarm persists, please contact ELETTRONICA SANTERNO’s Customer
Service.
