Description
Allows keypad "STOP" key to initiate motor stop during remote or serial operation (if
Stop key is programmed to Remote ON). If active, pressing "STOP" automatically
selects Local mode and initiates 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 voltage and frequency to the
motor is reduced at a rate set by "Decel Time".
Note: In REGEN mode, it is possible to cause an Overvoltage Trip if Note: In REGEN mode, it is ossible to cause an Overvoltage Tri if
Makes the keypad "FWD" key active in Local mode.
Makes the keypad "REV" key active in Local mode.
Makes the keypad "FWD" key active in Local Jog mode.
Makes the keypad "REV" key active in Local Jog mode.
Eight "Operating Modes" are available. Choices are: Keypad, Standard Run, 15 Speed, 2 Wire
Multi INP, 3 Wire Multi INP, Serial, Bipolar or Process Control. External connections
to the control are made at the J1B terminal strip (wiring diagrams are shown in
Section 3).
Selects the external speed reference to be used.
The easiest method of speed control is to select POTENTIOMETER and connect a 5K pot to
J1A-1, J1A-2, and J1A-3.
5 or 10VDC input command can be applied to J1A-4 and J1A-5.
4 TO 20 mA - If long distance is required between the external speed control and the control, the
4-20mA selections at J1A-4 and J1A-5 should be considered. Current loop allows
long cable lengths without attenuation of the command signal.
Note: JP1 jumper on the main control board must be in the correct position for current
or voltage operation. Refer to Figure 3-16.
10 VOLT W/TORQ FF - when a differential command is present at J1A-4 and 5, allows additional
torque feedforward input at J1A-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 expansion
board if installed.
5V EXB - selects optional High Resolution I/O expansion board if installed.
10V 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.
"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.
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 J1A-2 (referenced to J1A-1) to be used for reduction of the
programmed current limit parameter for torque trimming during operation.
"REGEN" to stop decelerates the motor too quickly. If a fault
occurs, increase the DECEL time.
