How To Stop The Procedure 'V/Hz Identification'; What Happens If A Fault Occurs During 'V/Hz Identification'?; Start Procedure 'V/Hz Identification' - Reliance electric GV3000/SE Instruction Manual

CAUTION: Current Limit (P.005) and Carrier Frequency (P.047) have to be set
correctly before activating the Identification procedure to avoid motor overloading
and/or overheating. Failure to observe this precaution could result in damage to or
destruction of equipment (e.g. motor damage).
CAUTION: During Identification procedure the motor can rotate reverse but only
one revolution (even with P.027 set to 1=REVERSE DISABLED). Uncouple motor
from any driven machinery that could be damaged by reverse rotation. Failure to
observe this precaution could result in damage to or destruction of equipment.
1. Uncouple motor from any driven machinery that could be damaged by reverse rotation.
2. Switch on the line voltage.
3. Check that important parameter values are correct before enabling 'V/Hz Identification Request':
• P.005 Current Limit
• H.000 Motor Nameplate Volts
4. The controller must not be running. Press the STOP/RESET key.

How to Stop the Procedure 'V/Hz Identification'

- If the procedure 'V/Hz Identification' is enabled (H.020 is turned ON, display shows I_En) but not
active, set H.020 to OFF.
- If 'V/Hz Identification' has been STARTED (display shows I_Ac), press the STOP/RESET key or
activate 'FUNCTION LOSS'.

What happens if a Fault occurs during 'V/Hz Identification'?

If FUNCTION LOSS or STOP is commanded,
no motor is connected, or
overcurrent is detected,
then the procedure is aborted, the drive will coast to rest, display shows an error message ('HId').
Check 'Result of Ident. Procedure' H.019. Refer to description for H.019 or Section 7.
If 'nId' is displayed and Identification procedure was never before executed (checked values =
Zero) and procedure is not enabled, then an ordinary drive START is performed: Reset fault,
enable 'Ident. Request' (H.020) and START the procedure. After completion of the procedure an
ordinary drive START will be accepted.

Start Procedure 'V/Hz Identification'

WARNING: The motor shaft can rotate in either direction by up to one (1)
revolution providing a minimum torque immediately after the Identification
procedure has been started. Stay clear of rotating machinery. Failure to observe
this precaution could result in bodily injury.
1. Enable the procedure 'V/Hz Identification' by setting H.020 to 'ON'. At display mode indication will be
'I_En'.
2. Press START key on the keypad. The display will show 'I_Ac' as long as the procedure is active.
Note: If the Identification procedure aborts, and HId is displayed, refer to above chapter or Section 7
for troubleshooting.
3. Once the procedure 'V/Hz Identification' is completed, parameter H.020 is set automatically to 'OFF'
and the display shows '0.00', the result can be checked as the value in H.019.
5 - 14
5 - V/HZ REGULATION MODE
(Check value in P.095. To be set correctly before
enabling procedure to limit output current and avoid
motor damage.)
To be set correctly before enabling procedure. After
any change of value in H.000 activate 'Ident.' procedure.
