Jog
A jog reference is usually used to run the motor at some preset, low speed. Two
separate jog speeds can be used as a speed reference - parameter 29 [Jog Speed 1]
or parameter 39 [Jog Speed 2]. A jog could be initiated by a Digital Input, by the
Logic Command word from a DPI adapter such as a HIM, or by the Logic
Command word from DriveLogix. In turn, a valid jog command initiated from
one of those adapters will turn on either bit 18 in parameter 152 [Applied
LogicCmd] to select jog speed 1 or bit 23 in [Applied LogicCmd] to select jog
speed 2. Note that the jog command is a maintained type of logic, so that the jog
speed will be active while the jog command bit is maintained.
Limit Generator
The limit generator generates a high and low limit based on an input.
• The input parameter 206 [LimGen X axis In] is a linkable destination. The
input range is 0.0000 to 1.0000.
• The output is equal to parameter 205 [LimGen Y axis Mn] when the input
is equal to 0.0000.
• The output is equal to parameter 204 [LimGen Y axis Mx] when the input
is equal to 1.0000.
• The output is available as a positive output parameter 207 [Limit Gen Hi
Out] and a negative output parameter 208 [Limit Gen Lo Out].
