◆ 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 and the selected speed is higher than d1-28 but lower than d1-29.
• Parameter d1-18 is set to 1 and a digital input programmed for Inspection Operation Speed [H1-xx = 54] is
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-xx = 50] and “Output Contactor
Control” [H2-xx = 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.

◆ Brake Sequence
WARNING! Sudden Movement Hazard. Be sure to set an acceptable deceleration time in parameter C1-09 [EmergencyStop
Ramp] when using the fast-stop feature. Rapid deceleration may cause the drive to fault on an overvoltage condition and lead to
an uncontrolled motor state. Failure to comply can result in death or serious injury
