FREQUENTLY ASKED QUESTIONS
GENERAL PURPOSE APPLICATION PARAMETERS
Question: How do I reset the drive back to factory default settings?
Answer: Go to parameter A1-03 and set value 2 2220 for 2 wire control or 3 3330 for 3 wire control
(Please refer to Step 6 for wiring diagram)
Question: How do I adjust the time it takes the motor to speed up or slow down?
Answer: Adjust the acceleration time parameter C1-01 and deceleration time C1-02.
Question: How do I prevent my drive from tripping on an O OV fault (overvoltage) while my motor is ramping down?
Answer: Increase deceleration time parameter C1-02.
Question: How do I prevent my drive from tripping on an O OL1 fault (overload) while my motor is ramping down?
Answer: Verify motor rated current parameter E2-01 and motor overload parameter settings
L1-01 Motor overload selection, L1-02 Motor overload protection time.
Question: I want to run my motor above the nominal motor speed?
Answer: Increase the value of parameter E1-04 Maximum Frequency

This step shows how to access and modify a A1000 parameter as
well as how to monitor A1000 signals such as output frequency
and motor current.
Make sure all protective covers have been re-attached and power
is turned on. D

To monitor output frequency and motor current or other signals
individually, press once, then press
. Next press to select monitor
Use to select monitor signal.

This step shows how to setup the sequence and reference method of the A1000. The sequence
method determines how the A1000 drive receives its start and stop command and the reference
method determines how the speed of the motor is controlled. Make sure all protective covers have
been re-attached and power is turned on. D
DO NOT RUN THE MOTOR.
This section may require you to change one or more A1000 parameters. Please refer to Step 5 for a
detailed explanation on how to change parameters.
SELECT START / STOP CONTROL METHOD
1. Start / Stop Control from Digital Operator
Go to parameter b1-02, set value to
b1-02
2. Start / Stop Control from external terminals (switch or relay contact)
Go to parameter b1-02, set value to ( Factory Default)
NOTE: It is beyond the scope of this document to program the A1000 drive for network communication control. Please refer
to the refer to the A1000 Technical Manual, (Document No. SIEP C710616 41) for this selection.
SELECT SPEED METHOD b1-01
(Factory Default)
1. Adjust motor speed / frequency from the Digital Operator
Go to parameter b1-01, set value to
2. Adjust motor speed / frequency from external terminals (0 - 10V / 4 - 20mA Signal)
Go to parameter b1-01, set value to (Factory Default)
