5. Operation
This section describes precautions that should be taken at test run and during
operation. For instructions on test run and operation, refer to XtraDrive Series
User Manual (P/N 8U0108).
5.1. Precautions at Test Run
CAUTION
#
To avoid accidents, run the servomotor only in test run (without load).
Failure to observe this caution could result in personal injury.
#
Before starting operation with a load connected, set up user constants suitable for
the machine.
Failure to do so could result in overrun failure. When the load moves vertically,
incorrect setting of the user constants could cause the load to fall.
#
Before starting operation with a load connected, make sure emergency-stop
procedures are in place.
Failure to observe this caution could result in personal injury.
5.2. Conducting Test Run for Servomotor Without Load
When the servomotor is operated without a load, set the speed loop gain
(user constant Pn100) to 40 or less. (The factory setting is 40.)
The speed loop gain (user constant Pn100) is determined by:
Load inertia
≥
servomotor inertia * (1 to 3).
Therefore, if the servomotor is rotated without a load (i.e., without load
inertia) or if the load inertia is small, the servomotor may oscillate.
To avoid this possibility, set the value of Pn100 (speed loop gain) to 40 or
less and then switch servo ON.
5.3. Conducting Test Run with Servomotor Connected to Machine
Initial parameters for XtraDrive are set assuming normal operation
conditions. Before conducting a test run, set up user constants suitable for the
machine.
Failure to do so could result in machine overrun or breakdown.
For the setting procedures and methods, refer to XtraDrive Series User
Manual (Cat. No. 8U0108).
The following items should be checked during the test run:
•
Unusual vibration
•
Abnormal noise
•
Excessive temperature rise
5.4. Precautions
During
Operation
CAUTION
#
During operation, do not touch the XtraDrive's heat sink.
Failure to observe this caution could result in burns.
Motor overload protection is provided internally. Refer to the XtraDrive Series Servo
System User Manual for rating.
