Trane TR1 6002 Installation And Operation Manual page 54

As long as there is a logic ‘1’ on the terminal selected for Speed Up, the
reference or the output frequency will increase by the Ramp-up Time
set in parameter 206.
As long as there is a logic ‘1’ on the terminal selected for Speed Down,
the reference or the output frequency will decrease by the Ramp-down
Time set in parameter 207.
Pulses (logic ‘1’ minimum high for 3 ms and a minimum pause of 3 ms)
will lead to a change of speed of 0.1% (reference) or 0.1 Hz (output
frequency).
Example:

No speed change

The speed reference frozen through the control panel can be changed
even if the drive has stopped. In addition, the frozen reference will be
retained in memory after power interruption.
Run Permissive. Run Permissive is used to require a second “run
permission” signal in addition to the normal run command, either in
Hand or Auto mode. When a run command alone is given, the display
will show RUN REQ., but the drive will not start. The drive can also
indicate that a run has been requested through one of the transistorized
or relay outputs. When, in addition to the run command, a logic ‘1’ is
applied to the Run Permissive terminal, the drive will run. If more than
one terminal is programmed for Run Permissive, a logic ‘1’ at any of
these terminals will allow the drive to run.
Jog is used to start the drive and run it at the frequency set in
parameter 209, Jog Frequency. Jog is active in both Hand and Auto
mode.
Jog is not active if a stop command has been given through the keypad
or terminal 27.
Data change lock is selected if changes to parameters are not to be
made via the control panel. It is be possible to change parameters
through the serial bus.

Pulse reference is selected if the frequency of a pulse train is to be
used as a reference signal. 0 Hz corresponds to parameter 204,
Minimum Reference. The frequency set in parameter 327, Pulse
Reference, Maximum Frequency corresponds to parameter 205
Maximum Reference.
Pulse feedback is selected if the frequency of a pulse train is to be
used as a feedback signal. Parameter 328, Pulse Feedback, Maximum
Frequency is the pulse frequency that corresponds to maximum
feedback.
Hand start is selected if an external signal is used to switch the drive
to Hand mode. A logic ‘1’ (Hand Start active) will start the motor. A logic
‘0’ will stop the motor. The drive will then be in OFF/STOP mode,
unless there is an active Auto Start signal from an external source.
Programming one of the digital inputs for Hand Start will disable the
LCP Hand Start and Auto Start keys.
WARNING
!
Unintended Start!
With Hand Start active, digital inputs may cause
drive to start at any time. The drive, motor, and
any driven equipment must be in operational
readiness. Failure to be in operational readiness
with Hand Start active could result in death,
serious injury, or equipment or property
damage.
Auto start is selected if an external signal is sent to switch the drive to
Auto mode. When a start signal is active on the control terminals or the
serial communication port, the drive will start the motor. If Auto Start and
Hand Start are active at the same time on the control terminals, Auto
Start will have the higher priority. If Auto Start and Hand Start are not
active, the motor will stop and the drive will then be in the OFF/STOP
mode. Programming one of the digital inputs for Auto Start will disable
the LCP Hand Start and Auto Start keys.
