 Inspection RUN
The inspection run can be activated in two ways:
1. A digital input can be used if parameter d1-18 = 1 or 2. Therefore a inspection speed must be set and any of
the digital inputs must be set to “Inspection Run Selection” (H1-=84) (see below).
2. A speed reference comparison value (parameter S3-19) decides if inspection run is activated or not. This
function work only if parameter d1-18 = 0 or 3 and if the inspection speed command is not assigned to any
digital input (H1-K84).

Inspection Run Selection by Digital Input
The inspection run digital input must be set before the Up/Down signal is set. During the start of the inspec-
tion RUN, the normal brake sequence is used and the inverter accelerates to the inspection speed (d1-14). The
stop method depends on the setting of parameter S3-03.
Inspection Speed Selection by Comparison Value
Using this function the inverter can detect the inspection speed by the selected speed reference. The speed
must be selected before the Up/Down signal is set. If S3-04 < selected speed O S3-19 the selected speed is
regarded as inspection speed. The normal start sequence is used, the stop method depends on the setting of
parameter S3-03.
Inspection Run Stop Behavior
S3-03 = 0.0 sec., Stop without deceleration ramp
The inverter stops when the Inspection Speed command or the Up/Down command is removed. In this case:
• The inverter output is cut by baseblock immediately
• The brake open signal is removed immediately
• The contactor control output is removed immediately
