Possible Causes & Corrective Action
Ready, Waiting
For Drive
(operator)
The operator is waiting to establish
communications with the drive’s
control board.
Normal, if displayed momentarily
➲
No action is required, if the message
disappears shortly after power-up of the
operator.
Bad Connector Connection
➲
Remove and re-seat the operator in its
cradle.
➲
If re-seating of the operator does not work,
the operator or the drive’s control board may
need to be replaced.
Ser2 Spd Flt
[closed-loop]
This fault is declared if the SER2 INSP
SPD (A1) or SER2 RS CRP SPD (A1)
parameters have exceeded contract
speed (CONTRACT CAR SPD (A1)
parameter).
Check Parameters Settings:
➲
Check SER2 INSP SPD (A1) parameter, if
greater than CONTRACT CAR SPD (A1)
parameter.
➲
Check SER2 RS CRP SPD (A1) parameter, if
greater than CONTRACT CAR SPD (A1)
parameter.
