Event Control Parameters
The Event Control Parameters (C1-CNTL1...C9-CNTL9) define the direction, speed, acceleration/
deceleration time and duration of each program step. Each is programmed as a string of 8 characters or
“bits.” Figure 4.1 defines the bit coding:
Event Count Parameters
The Event Count Parameters (E1-ECNT1...E9-ECNT9) define the duration of each program step. Each
Event Count Parameter is associated with a corresponding Event Control Parameter (That is parameter E1-
ECNT1 determines the duration of C1-CNTL1; E2-ECNT2 determines the duration of C2-CNTL2, etc.). The
data entered can represent time, pulse counts, digital comparison or an analog voltage level as defined in
Table 4.1. The range of data that can be entered in each Event Count Parameter is 0 to 65,000.

PROGRAM DATA
NOTES:
1. When data codes 1-29 are invoked, 81-PRGNO will
revert to "0" upon exiting the program mode. When
data codes greater than 29 are used, 81-PRGNO will
retain the data setting.
2. Data code 1 allows all program parameters to be
returned to factory defaults. When the program mode
is exited, the display will indicate "INIT
PARAMETERS" then "RESTART".
3. Data code 2 allows storage of the current set of
program parameters. Data code 3 allows a previously
stored set of program parameters to be retrieved. Data
code 4 allows the current and stored set of program
parameters to be exchanged.
4. Data code 5 allows the WFC2005-0x to be re-
calibrated for use on a 3 HP motor when powered
from a single phase source. Use data code 1 to return
to the 5 HP calibration.
5. Parameter 21-MODE must be set to a code that
permits MODE 2 (REMote) operation. Also, the drive
must be operated in REMote mode.
6. Data codes 32 and 33 select the WFC HT 's EMOP control programs. With code 32 selected, commanded output
frequency returns to 31-FMIN when the drive is stopped. With code 33 selected, commanded output frequency
remains at the previous setpoint. See the table above for proper usage.
7. These codes permits both speed and direction control from an analog speed input. Order Form 1042 for more
details.

Program Sequencer
The Program Sequencer function can be thought of as a simple programmable logic controller (PLC). It
permits the drive to execute up to nine (9) sequential program steps. Each program step can be an
independent combination of direction, speed and ramp. The duration of any one program step can be
controlled by: time, digital comparison, pulse (event) count or an analog voltage level. Use of the pulse count
and voltage level comparisons requires the use of either the WPC04 – Encoder Interface Board or WPC05 –
Process Control Interface Board (see Table 4.2 for details). An Event Control parameter (C1-CNTL1...C9-
CNTL9) and an Event Count parameter (E1-ECNT1...E9-ECNT9) serve to define each program step
independently.
