◆ Inspection Operation

Start Condition in Inspection Operation
■
NOTICE: Always turn off the RUN command before changing the setting of parameters d1-18 (Speed Reference Selection Mode),
b1-01 (Speed Reference Selection), or H1-
settings, the motor may unexpectedly start running, and could result in injury.
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- = 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- = 50) and "Output Contactor 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.
