ENCODER
SETUP::MOTOR CONTROL::ENCODER
This block is used to set up the way that speed feedback is obtained via the feedback option card. Different encoder types may be selected including
pulse encoder, sincos encoder and absolute single turn or multi turn. Different encoder types require different hardware options. If an encoder type
is selected which does not match the hardware, an error will be flagged.
Parameter Descriptions
PULSE ENC VOLTS PREF: 71.01 Default: 10.0 V Range: 10.0 to 20.0 V
Set this approximately to the supply voltage required by the pulse encoder.
SINCOS ENC VOLTS PREF: 71.22 Default: 5.0 V Range: See below
Used to set the supply volts required by the sin/cos encoder.
Enumerated Value : SinCos Encoder Volts
0 : 5V
1 : 10V
ENCODER LINES PREF: 71.02 Default: 2048 Range: 250 to 262143
The number of lines must be set to match the type of encoder being used. Incorrect setting of this parameter will result in an erroneous speed
measurement and will cause the motor to become unstable.
ENCODER INVERT PREF: 71.03 Default: FALSE Range: FALSE/TRUE
Used to match the encoder direction to the motor direction. The encoder direction is set automatically by the Autotune when running in closed-loop
vector mode. It should not be necessary to adjust this parameter. When TRUE, changes the sign of the measured speed and the direction of the
position count.
