Generate motor contactor control output.
Exit to state 0:
• Fast Disable (B27) = Off (0) AND
• Total Output Current (J22) < 25 % of rated current AND
• F10 T31 STO Input 1 State (F10)= Off (0) AND
• There is no digital speed signal present (if used) AND
• There is no direction signal present (in dual direction signal mode) AND
• The Fast disable input (if used) = Off (0) OR
• The drive trips
The following error detection is made in this state after 4 s. The list is in order of priority:
1. If Motor Contactor Monitoring Enable (B29)= On (1), and it takes > 4 s for the monitoring input to be set to 0, generate a Trip 71 (Mot con
closd).
2. If the Fast Disable (B27) input terminal = On (1), then generate Trip 65 (Fast disable err).
3. If the F10 T31 STO Input 1 State (F10) = On 1, then generate Trip 66 (STO Ctrl err).
4. If the total current is > 25 % of rated, then generate Trip 67 (Current on stop).

Troubleshooting and identifying faults

Reported fault
Output motor contactors are
not closing during the static or
rotating autotune.
Motor brake is not releasing
during rotating autotune
Motor data incorrect
Unable to carry out
autotune, motor does
not rotate
Encoder data incorrect
STO) Safe Torque Off, Drive
enable not active
Rotating autotune not possible

Contactor control
Root cause
Verify where the output motor contactor control is being carried out, on the drive or the
Elevator controller. Select the autotune required and then ensure the output motor
contactors are closed.
• Refer to Menu B Motor for the motor contactor control and to select the autotune
Verify where the brake control is being carried out, on the drive or the Elevator
controller. Select the autotune required, close the output motor contactors and then
release the motor brake.
• Refer to Menu D Brake for the brake control and Menu B Motor to select the
autotune.
Verify motor nameplate data and parameter settings in parameters B01 through to B10.
Ensure correct operating mode is also selected for motor type, Induction motor or PM
motor
• Refer to Menu B Motor for motor parameters
Verify encoder data and parameter settings in parameters C01 through to C08 for
Closed loop operation. Note that for encoders with an additional comms interface e.g.
SC.EnDat an auto configuration option is available in parameter C02.
• Refer to Menu C Encoder for encoder parameters
For PM motors and operation in RFC-S an encoder phase angle test must be
completed before operation.
• Refer to Motor Autotune (B11)
Check the enable signal is connected to control terminal 31 of the drive. The enable is
typically connected via the auxiliary contacts on the output motor contactors therefore
these must operate in order the drive to be enabled.
• Check motor contactor control in Menu F Hardware IO and the connections to
control terminal 31 of the drive.
A rotating autotune cannot be carried out where there is either insufficient space for the
Elevator car to move in the Elevator shaft or load is present resulting in an unbalanced
system.
• In this condition a static autotune should be carried out refer to Motor Autotune
(B11).
