Some backlash may be unavoidable, especially when gear reduction is used. If backlash is present, the inertia match must be good (load inertia should be roughly equal to motor inertia) for good servo performance. Gearing reduces the inertia reflected to the motor by the square of the gear reduction from motor to load. Therefore, select a gear ratio to give the required match.

There can be cause for concern when this p-p number exceeds 40% of the drive’s or motor’s current rating. The motor current should be monitored using Dac Monitors on J2-4 to insure actual ripple current, with ARF0/ARF1 filtering, is not excessive.

Motor current ripple can often be reduced by lowering the ARF0, ARF1 low-pass filter break frequencies. This benefit is limited by velocity loop bandwidth and stability constraints. Velocity feedback ripple, and hence motor current ripple, can also be reduced by specifying a higher accuracy resolver.

DCS or TDCS
(1) Distributed control system DCS and distributed control system TDCS are integrated 4C (Communication, Computer,
A monitoring technology that integrates Control and CRT technologies.
(2) A tree like topology system from top to bottom, where communication is the key.
(3) In the interrupt station, PID connects the computer with on-site instruments and control devices.
(4) It is a tree topology and parallel continuous link structure, with a large number of cables running parallel from relay stations to on-site instruments and meters.
(5) Analog signal, A/D-D/A, mixed with microprocessor.
(6) One instrument is connected to the I/O line by line and connected to the local area network LAN by the control station.
(7) DCS is a three-level structure consisting of control (engineer station), operation (operator station), and on-site instruments (on-site measurement and control station).
(8) The disadvantage is that the cost is high, and the products of each company cannot be interchanged or interoperated. The large DCS system is different from each other.
(9) Used for large-scale continuous process control, such as petrochemicals.
(10) Manufacturers: Bailey (USA), Westinghouse (USA), HITACH (Japan), LEEDS&
NORTHRMP (USA), SIEMENS (Germany), Foxboro (USA), ABB (Switzerland), Hartmann&
Braun (Germany), Yokogawa (Japan), Honeywell (USA), Taylor (USA), etc.
