10.6 Encoder Sensor Group
z
Pr.188
Î
Encoder Sensor Direction
If observe the signals A and B (of the Encoder Sensor output):
z
If motor is running in forward direction, the A signal leads the B signal, then Pr.188 should set 0.
z
If the A signal lags the B signal, then Pr.188 should set 1.
If observe Pr.191 (Encoder Sensor Counter Status) status:
z
If motor is running in forward direction, the counter value is increased, and then Pr.188 should set 0.
z
If the counter value is decreased, then Pr.188 should set 1.
z
Pr.189
Î
Encoder Sensor PPR
Input the Encoder Sensor ppr value in this parameter.
z
Pr.190
Î
Encoder Sensor A/B/C Status
This parameter displays the status of A/B/C of encoder sensor.
【NOTE】About the detail of this status, please contact with agency or technical department of factory.
z
Pr.191
Î
Encoder Sensor Counter Status
This parameter displays the encoder sensor counter status. The counter will increase when
receive a forward direction pulse, and decrease when receive a reverse direction pulse. The
range of the counter is 0 ~ 65535.
z
Pr.192
Î
Encoder Sensor Input Buffer Size
If using 256 pps sensor, Pr.192 should set 6.
If Using 1024 pps sensor, Pr.192 should set 2.
z
Pr.193
Î
ENCODER CHECK TIME
This parameter is used to set the check time for driver to check the PG signal at every time the
speed command be send to check if the encoder sensor is in good condition. Every time the
driver send a speed command to motor, and after the time which is set in this parameter the
driver will check the motor’s speed by checking the encoder sensor feedback, if the speed is
not match the command the driver will show PG alarm message. This function can be disabled
by setting 0 into this parameter.
z
Pr.194
Î
Encoder type
This parameter is used to select proper encoder type for used.
Pr.194 Encoder type
0 JPS MAG-C Encoder (Recommand)
Note:The Encoder type 1 and 2 uses the ABZ to deliver the UVW status within 5 or 500 ms when
power on starts. After the 5 or 500ms period, the output signals of ABZ will change to present
normal AB phase pulses and Z index.
z
Pr.354
Î
Actual Counts Per Revolution
This parameter displays encoder feedback pules per revolution ，range = 0 ~ 65535。
