Inspection Operation
Start in Inspection Mode
Inspection operation is performed when an Up or Down signal is input while one of the
conditions below is true.
• Parameter d1-18 is set to 0 and the chosen speed is higher than d1-28 but lower than d1-29
• Parameter d1-18 is set to 1 or 2 and a digital input programmed for Inspection Operation
Speed (H1-
= 54) is enabled.
The start is performed using the same acceleration characteristics, brake sequence and
contactor sequence as in normal operation. The carrier frequency is set to 2 kHz during
Inspection Operation.
Stop in Inspection Mode
To stop the drive in Inspection Mode either remove the Up or Down signal or deselect the
Inspection Operation Speed Reference.
The stop can be performed using a deceleration ramp, depending on the setting of parameter
C1-15 (Inspection Operation Deceleration Ramp).
• If C1-15 = 0, the drive immediately closes the brake, shuts off drive output and opens the
motor contactor (if controlled by the drive).
• If C1-15 > 0, the drive decelerates to stop with the selected ramp, closes the brake, shuts
the output off and opens the motor contactor (if controlled by the drive).
