In this video we will hook up a SureServo system and quickly jog the motor to
verify proper operation.
You will need a SureServo drive,
a SureServo motor,
a motor power cable,
motor feedback cable,
and a power source.
Most importantly you should have a copy of the SureServo manual.
You can purchase a copy of the manual,
or you can download it for free from the automationdirect.com Web site,
or the SureServo.com Web site.
Hooking up a SureServo systems is easy.
The encoder cable connects to the motor lead
and to the drive.
The motor power cable is connected to the other motor lead and then to the drive
with three discrete connections and the ground.
Please note that unlike some other three-phase motors
the phases for a servo must be connected in the correct order.
On a SureServo
red is connected to “U”
white to “V” and black to “W”.
The green ground wire has a ring terminal pre-installed and is attached
at the bottom front of the drive.
If you have a brake motor
refer to chapter three for details on connecting the brake leads.
Note that all AutomationDirect motor power cables include the brake leads
regardless of whether your motor has a brake
If your motor has a brake you will need to apply 24 Volt DC to these
leads
before you can jog the motor.
This motor doesn't have a break so I have just capped these leads.
Two types of power connections are required for most Servo systems
and SureServo is no exception.
The main power connection powers the motor
while a second connection powers the control electronics in the drive.
In many installations an e-stop circuit is required to disconnect the
main power
“R”, “S” and “T”,
while control power to the drive can be maintained for diagnostic and
maintenance purposes.
It is strongly recommended that you implement an e-stop circuit and
proper circuit protection.
Both for personnel safety
and for the protection of the electronics.
See chapter three of the manual for recommendations on the size and type of
circuit protection
for each SureServo system.
Most SureServo installations will require Three-phase 220 Volts for the
main power.
Although the smaller systems will run on Single-phase 220.
In this case supply power to “R” and “S” only.
The control power
only requires single-phase. Just provide 220 volts across the “L1” and
“L2” terminals.
Double-check your wiring - make sure you've got the required voltage on the
correct connectors.
Let’s power it up.
There will be errors
alarm fourteen and alarm fifteen are alarm errors for the over travel limit
switches
see chapter eight for an explanation.
The drive is configured for normally closed limit switches by default and we
don't have any switches connected, thus, these errors.
Now we will set some parameters.
First we’ll set P2-08
to ten.
This will reset the drive to factory defaults.
Press the mode once then press next until P2-00 appears
press the arrow up key until P2-08
is selected, press enter.
Then press the arrow up until a value of ten is displayed.
Press enter to accept.
See chapter four for additional keypad help.
Next we will set the appropriate motor code.
Because each sure servo drive is capable of controlling several different motors
we must tell the drive which motor is connected.
We will set P1-31
to eleven for this two hundred watt motor.
See chapter five for all of the motor Codes.
Now we must cycle power to the drive.
Warning: To prevent serious injury or damage to equipment always start any
new servo setup
with the motor shaft disconnected from the load.
In this quick start video we will bypass mechanical over travels
Please disconnect the load for the first test of the motor
Always wire an e-stop circuit into the power feed for the drive.
Always drop the main incoming power for e-stop conditions
but remember the control power can remain on.
Now we will set parameter P2-30
to one.
This temporarily overrides servo enable, clockwise limit, and counterclockwise
limits.
This parameter will revert to zero if control power is cycled.
This feature is purely for testing purposes.
You should discreetly wire a Servo enable
and over travel limit switches if appropriate for your application.
If your application doesn't require over travels you can disable the respective
inputs or use them for another purpose.
The motor is now enabled.
To jog the motor go to P4-05: Jog Operation.
Press Enter.
The Jog speed set point is displayed.
The default is twenty RPM.
Press enter again to enter the jog operation mode.
The LED display will show jog.
Press the up arrow or the down arrow to jog the motor
forward or reverse.
Press mode to return to the jog speed selection.
Let’s increase the jog speed upward.
Press enter to select the speed and to re-enter the jog operation mode.
Again the arrow keys now allow jogging of the motor.
Press mode to exit the jog operation.
When you have finished jogging the motor you should cycle control power to the drive.
This will reset P2-30 re enabling the Servo enable,
the clockwise limit, and the counter clockwise limit inputs.
The other changes we've made such as the motor type and the jog speed will be
retained.
