YA[N] - Auxiliary Position Sensor Parameters
Purpose:
Defines the behavior and direction of the auxiliary position sensor signals.
YA[4] can specify that the auxiliary encoder pins will be outputs, repeating the pulses of
the main position incremental or analog sensors. When a main position feedback is by
analog sensor, encoder emulation signals are produced. This mode is used to enable
other drives to follow, without electrically overloading the main position sensor or to
produce pulse width modulation signals (PWM and polarity signals).
YA[4] can also specify that the encoder pins serve as input, following the pulses of the
external position incremental sensor or PWM source signals. This mode is used to enable
the drive to follow any source of encoder or PWM signals.
Index Description
1 Emulation scale factor 2 N : N=[0...4]
The amount of emulated encoder pulses and velocity value will be divided by 2 N .
2 Reserved.
3 Reserved.
4
Auxiliary encoder type:
0: Auxiliary encoder entry used as input for external pulse-and-direction signals
1: Not used
2: Auxiliary encoder entry used as input for external quadrature
incremental encoder signals
3: Reserved
4: No auxiliary encoder inputs; the auxiliary encoder pin output repeats the
main encoder input or produces an emulated encoder signal for drives with
analog encoder or resolver feedback options.
5: 50% duty cycle command format. 0% and 100% duty cycle is interpreted
as either maximum positive or negative PWM command depending
upon the YA[5] setting.
6: 100% duty cycle command format. Depending upon command
polarity signal level, 100% duty cycle is interpreted as either maximum
negative or positive PWM command.
7: Auxiliary encoder port used as generator of the PWM signals
5
Auxiliary count direction:
0: Count forward for encoders or P&D inputs.
For PWM inputs: forward direction, increasing the duty cycle causes
an increase of the controller output command.
1: Count in reverse direction for encoders or P&D inputs.
For PWM inputs: reverse direction, increasing duty cycle causes a decrease of the
controller output command. YA[5] has no effect if YA[4] specifies that the auxiliary
encoder pins repeat outputs (YA[4]=4).
