SPD
COMMAND
SRC
(Speed Command Source)
This parameter designates the source of the
drive’s speed command. The four possible
sources for the speed command are following:
• Serial Channel - a RS-422 serial port located
on the customer interface PCB.
• Analog Channel – a bipolar (±10V) signal.
Available with the analog channel is a Speed
Command Multiplier (SPD COMMAND
MULT(A1)) and Speed Command Bias (SPD
COMMAND BIAS(A1)). These parameters
are used to scale the user’s analog speed
command to the proper range for use by the
drive software.
• Multi-Step Command - user defined fifteen
discrete speed commands (CMD1 - CMD15
in A3 submenu). Four logic inputs are used
as speed command selections. CMD0 is
reserved for zero speed, but the user can
specify CMD1 - CMD15 to be any speed
command either positive or negative. See
Multistep Ref A3 on page 41.
• Ser Mult Step Command - user defined
fifteen discrete speed commands (CMD1 -
CMD15 in A3 submenu). Four bits in the
serial protocol are toggled to run multi-step
serially. See Multistep Ref A3 on page 41.

RUN
COMMAND
SRC
(Run Command Source)
This parameter allows the user to choose the
source of the run command from one of the
following sources: an external run signal from a
logic input (external tb), a run signal transferred
across a serial channel (serial), or a signal from
both the serial channel and a logic input
(serial+extrn). If a signal is required from a logic
input (either externaltb or serial+extrn), the Run
signal on TB1 must be selected.

FIELD ENA
SOURCE
(Field Enable Source)
Enabling the Field Source initially turns on the
Line Side Boost, than establishes a field. This
may be done through a logic input (set FIELD
ENA SOURCE to EXTERNAL TB), serially, (set
FIELD ENA SOURCE to SERIAL), by the run
command (set FIELD ENA SOURCE to
ENABLE ON RUN), or by 2-bit serial. 2-bit
serial uses two bits given to the drive serially to
control the field. See the table below for the bit
options. Bit 1 refers to Full Field bit while Bit 0
refers to Standby Field Bit. While the motor is
running, both Boost and Field are on.
