(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 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 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.
