速度或扭矩回路可從模擬電壓源接收其指令，并可選擇通過(guò)OPMODE變量。SERVOSTAR CD-Lite的模擬輸入是差分的。這意味著兩個(gè)輸入端接收到的信號(hào)彼此相減以產(chǎn)生“差”

Resolver Systems
The output signal is developed through the R/D hardware circuitry for minimal phase lag and has
a maximum frequency determined by the motor speed and R/D limits. It provides a configurable
(ENCOUT) resolution of up to 16384 lines (65536 quad counts) per revolution of the motor
shaft. The placement of the index pulse (INDEXPOS) can be varied on resolver systems within
360 electrical degrees of the feedback signal. For single-speed resolvers, this means you can vary
the position of this signal over one mechanical revolution. For multi-speed resolvers, the
mechanical position variation is determined by the pole-pair count of the resolver (e.g. threespeed resolver gives mechanical variation of the pulse within 1/3 of a revolution).
Encoder Systems
The output signal is the actual encoder feedback signal that is pre-configured (MENCRES) in the
drive’s motor parameters. It can be scaled down by multiples of two (ENCOUTO: 1, 2, 4, 8, 16)
and has a maximum frequency limit of 3 MHz. Used to indicate an abnormal operating state:
If the position hold feature is active, the OPMODE number will flash at a 1 Hz
rate.
If a fault was detected, a flashing code will be displayed to identify the fault.
Some codes consist of a sequence of two or more digits (see Troubleshooting
section). In general, these faults will cause a latched disable (sometimes
controllable through software switches). To clear fault, toggle remote enable
(except for OverCurrent).
If the encoder initialization function (ENCSTART) is active, the OPMODE
number will flash at a 3 Hz rate. The SERVOSTAR CD-Lite has the ability to assume different modes of operation. It is factory
configured in OPMODE=1 (Analog Velocity Controller) but may be reconfigured by the user. Not all
commands and variables are active or meaningful in every OPMODE.
OPMODE = 1 Analog Velocity Controller. The SERVOSTAR CD-Lite is configured as a
velocity-loop controller and is controlled via a ± 10V analog input signal.
The commanded velocity is proportional to the input voltage.
OPMODE = 3 Analog Torque (Current) Controller. The SERVOSTAR CD-Lite is
configured as a torque-loop controller and is controlled via a ± 10 V analog
input signal. The commanded current is proportional to the input voltage.
System I/O
This section discussions the I/O features of the C3 connector (except for the Thermostat input on C2 see
appendix). Electrical specifications are in the Quick Start Guide.
Analog Input (ANIN1)
The velocity or torque loop can receive its command from an analog voltage source and is selectable
through the OPMODE variable. The analog input to the SERVOSTAR CD-Lite is differential. This
means that the signals received at the two inputs are subtracted from each other to create a ‘difference,’
that is used to command the rest of the system. This type of input has a high degree of noise immunity
and, in many cases, will allow for ground isolation between systems. This analog input also has a low
pass filter (ANLPFHZ) to prevent high frequency noise from entering the system.
