SECURITY INHIBIT
For protection of the programmed variables that make up either parameter table, when this function
is turned on, the operator can only change the set point or ratio parameters, PS1 and PS2, or PS3 and
PS4. This prevents accidental changes of the parameter values.

"OPLP" ERROR CODE
When using the DS9000 as a Follower controller, the "OPLP" error code will be displayed when the
following error becomes excessive. The DS9000 is no longer maintaining a "position lock" between
the controlled motor and the reference signal. The DS9000 will continue to maintain closed loop
speed control. To reset, remove the Start input and then re-apply the Start input. TB1-7 is an open
collector output and the user must supply a DC supply, (See Figure 1 for details) to operate a relay
connected to this terminal point. When the relay is dropped out, this indicates normal operating
conditions. When the relay is picked up, "OPLP" open loop or excessive following error has occurred.
When used as a master or Set-Point controller, the OPLP message does not indicate an error
condition. (See Section 2.7.1.2 on Dip Switch #2).
TB1-7
Connect a DC supply voltage and a relay coil in series between TB1-7 and signal
common (TB1-9 or TB1-12). When the fault "OPLP" occurs, then the open collector
output TB1-7 will provide a complete circuit and the customer supplied relay will
pickup. (Always use a diode (1N4002-7) in parallel with the relay coil as shown in
Fig. 1.)
2.7.3
SET-UP ADJUSTMENT PARAMETERS
To simplify the startup procedures for the DS9000 and motor controller, general or default values
have been assigned to the operational parameters. There are seventeen operational parameters that set
all of the variables required for the DS9000. Typically four of these are used during system operation.
These are four preset speed parameters, PS1, PS2, PS3 and PS4. The others are set during the initial
system startup and do not require further adjustment.
CAUTION:
Do not use the PROG mode to check parameter values while operating your motor drive system as
improper system operation may occur. Any changes to the contact inputs on TB1 will not be
recognized until you go out of PROG mode. In addition, go out of the PROG mode before restarting
the DS9000. The motor will not restart until you go out of PROG mode. If the tach LED is flashing,
PROG mode is active, press the PROG key to move out of PROG mode.
To check the parameter values, follow these steps.
1. Apply AC power to the DS9000 but do not start up the DS9000 or motor controller. On the
display you will see the speed value programmed in the active preset. If there are no connections
to TB1-4 and 5, this will be PS1. The active preset will have a dash between the PS and the
number. By pressing the PROG key, you will enter the program mode. Any time you are in
program mode, the mode that allows you to change the parameters, the Tach LED will blink. If
TB1-6 is connected to circuit common (either TB1-9 or TB1-12), open this connection to turn off
the security protection. This will allow you to view the parameters when in the OFF position (no
Start Input). The speed or ratio parameters, PS1, PS2, PS3 and PS4, are the only parameters that
can have their values changed when you are not in the program mode.
26
When the Start input is off all parameters can be changed. When the Start
input is on, the first eight parameters can be changed, PS1, PS2, PS3, PS4
LO, HI, Acel or Decl.
set-point or ratio parameters can be changed, PS1, PS2, PS3 or PS4.
