4.1.5 Trial Operation for Servomotor with Brakes
Holding brake operation of the servomotor can be controlled with the brake interlock output (/BK) signal of the servo drive.
When checking the brake operation,take advance measures to prevent vibration due to gravity acting on the machine or
external forces. Check the servomotor operation and holding brake operation with the servomotor separated from the
machine.If both operations are correct, connect the servomotor to the machine and perform trial operation.
4.2 Control Mode Selection
The control modes supported by the ETS series servo drives are described below.
Speed Control (parameter reference)
Controls servomotor speed using parameter reference. Use in the
following instances.
·To control speed
·For position control using the encoder feedback divisionoutput from
the servo drive to form a position loop in the host controller.
Position Control(Pulse train reference)
Controls the position of the servomotor using pulse train position
reference.
Controls the position with the number of input pulses, and controls the
speed with the input pulse frequency.
Use when positioning is required.
Speed Control(contact reference) Speed Control
(zero reference)
Use the three input signals /P-CON，/P-CL and /N-CL to control the
speed as set in advance in the servo drive.
Three operating speeds can be set in the servo drive. (In this case, an
analog reference is not necessary.)
These are swiching modes for using the four control methods
described above in combination. Select the control method switching
mode that best suits the application.
