Description
Allows keypad STOP key to initiate motor stop during remote or serial operation (if Stop
key is set to Remote ON in Standard Run, 15 Speed, Bipolar, Serial and Process
Control modes). If active, pressing STOP automatically selects Local mode and initi-
ates the stop command.
Selects if the Stop command causes the motor to COAST to a stop or REGEN to a stop.
In COAST, the motor is turned off and allowed to coast to a stop. In REGEN, the volt-
age and frequency to the motor is reduced at a rate set by Decel Time. age and frequency to the motor is reduced at a rate set by Decel Time.
ON makes the keypad FWD key active in Local mode.
ON makes the keypad REV key active in Local mode.
ON makes the keypad FWD key active in Local Jog mode.
ON makes the keypad REV key active in Local Jog mode.
The STOP input at J1-11 in the Keypad mode is enabled (when ON).
Ten "Operating Modes" are available. Choices are: Keypad, Standard Run, 15SPD,
Serial, Bipolar, Process, 3 SPD ANA 2 wire, 3 SPD ANA 3 wire, EPOT - 2 Wire and
EPOT - 3 Wire. External connections to the control are made at the J1 terminal strip
(wiring diagrams are shown in Section 3 "Control Circuit Connections").
Selects the external speed reference to be used.
The easiest method of speed control is to select POTENTIOMETER and connect a 5KW
pot to J1-1, J1-2, and J1-3.
±5, ±10VDC or 4-20mA input command can be applied to J1-4 and J1-5.
If long distance is required between the external speed control and the control, the 4-20mA
selections at J1-4 and J1-5 should be considered. Current loop allows long cable lengths
without attenuation of the command signal.
10 VOLT W/TORQ FF - when a differential command is present at J1-4 and 5, allows addi-
tional 5V torque feedforward input at J1-1, 2 and 3 to set a predetermined amount of
torque inside the rate loop with high gain settings.
EXB PULSE FOL - selects optional Master Pulse Reference/Isolated Pulse Follower ex-
pansion board if installed.
5VOLT EXB - selects optional High Resolution I/O expansion board if installed.
10VOLT EXB - selects optional High Resolution I/O expansion board if installed.
4-20mA EXB - selects optional High Resolution I/O expansion board if installed.
3-15 PSI EXB selects optional 3-15 PSI expansion board if installed.
Tachometer EXB- selects optional DC Tachometer expansion board if installed.
Serial -selects optional Serial Communications expansion board if installed.
None - Used in Process Control mode, two input configuration with no Feedforward input.
Note: When using the 4-20mA input, the JP2 jumper on the main control board
"OFF" will cause a low input voltage (e.g. 0VDC) to be a low motor speed command and
a maximum input voltage (e.g. 10VDC) to be a maximum motor speed command.
"ON" will cause a low input voltage (e.g. 0VDC) to be a maximum motor speed command
and a maximum input voltage (e.g. 10VDC) to be a low motor speed command.
Provides an offset to the Analog Input to minimize signal drift. For example, if the
minimum speed signal is 1VDC (instead of 0VDC) the ANA CMD Offset can be set to
-10% so the minimum voltage input is seen by control as 0VDC. The value of this
parameter is automatically adjusted during Autotune "CMD Offset Trim" test.
Allows a defined range of voltage to be a deadband. A command signal within this
range will not affect the control output. The deadband value is the voltage above and
below the zero command signal level.
Allows the 5V input at J1-2 (referenced to J1-1) to be used for reduction of the
programmed current limit parameter for torque trimming during operation.
