◆ Inspection Operation

■
Start Condition in Inspection Operation
Inspection operation is performed when an Up or Down signal is input while one of the following conditions is true:
• Parameter d1-18 is set to 0 or 3 and the selected 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-
enabled.
Inspection Operation uses the same acceleration characteristics and brake sequence at start as normal operation.
The carrier frequency is set to 2 kHz during Inspection Operation, but can be changed using parameter C6-21.
■
Stop Condition in Inspection Operation
To stop the drive during Inspection Operation, either remove the Up or Down command or reset the input terminal for
Inspection Operation.
A deceleration ramp can be set for Inspection Operation using parameter C1-15.
• If C1-15 = 0.00, the drive immediately applies the brake, shuts off the drive output, and opens the motor contactor, i.e.,
the multi-function output terminals set for "Brake Control" (H2-
51) are cleared.
• If C1-15 > 0.00, the drive decelerates to stop at the rate set to C1-15, then applies the brake, shuts the output off, and
opens the motor contactor.
