Detailed Drive Operation Chapter 1
Decel Time
Parameter 33 [Decel Time 1] sets the rate at which the drive ramps down its
output during a ramp Stop command or during a decrease in commanded speed.
The rate established is the result of the programmed deceleration time and the
programmed motor rated speed set in parameter 4 [Motor NP RPM] as follows:
Times are adjustable in 0.0001 second increments from 0.01 to 6553.5 seconds.
Programming zero seconds will cause the drive to use 0.1 second.
Digital Inputs
Technical Information
There are a total of six Digital Inputs.
• Digital Input 1 and Digital Input 2 are 12V DC or 24V DC, Sinking, Hi-
Speed. They are configured for 12V DC or 24V DC via dip switches
(default 24V DC). Use Digital Input 1 and Digital Input 2 for position
registration.
• Digital Input 3 is 24V DC, Sinking.
• Shared Common for Digital Inputs 1, 2 and 3.
• Digital Inputs 4, 5 and 6 are 24V DC or 115V AC, Sink/Source. They are
configured for 24V DC or 115V AC via dip switches (default 24V DC).
• Shared Common for Digital Inputs 4, 5 and 6.
• Digital Input 6 is a Hardware (HW) Enable by default. A jumper is used to
disable the HW Enable and use Digital Input 6 for other functions.
