116Homing OperationDetect the home sensor (at the front end) in a direction of homing by 16.Pr30 (Homing speed (high)), get outof the home sensor area once and detect the home sensor (at the front end) by 16.Pr31 (Homing speed(low)) again. After that, count the Z phase specified times by 16.Pr3B (Homing Z-phase count setting) anddefine that point as a home position.(1) A starting point is between the home sensor and negative direction limit sensor (also on the negative direction limit sensor)Positive direction limit sensor Negative direction limit sensorHome sensorDirection of homingZ phaseL-SPDL-SPDL-SPDL-SPDH-SPDH-SPDH-SPDH-SPDH-SPD(2) A starting point is on the home sensor(3) A starting point is between the positive direction limit sensor and home sensor(4) A starting point is on the positive direction limit sensorHome Sensor + Z Phase (based on the front end)Example: Z phase count = 3 at an operation in a positive directionDescription Specify the high speed for the homing operation (0 to 6000 r/min). Specify the low speed for the homing operation (0 to 6000 r/min). Specify the offset operation speed if the home offset operation is performed (0 to 6000 r/min). For the homeoffset operation, refer to page 124. Specify the acceleration for the homing operation in a range between 0 to 3000 r/min. Specify the deceleration for the homing operation in a range between 3000 to 0 r/min. Specify an operating direction for the homing. (0: positive direction, 1: negative direction) Specify a type of homing. ([0]: Home sensor + Z phase (based on the front end)) Specify whether or not to perform the home offset operation. (0: Not perform, 1: Perform) For the home offsetoperation, refer to page 124. Specify the Z phase that an operation stops. ([3] (the 3rd Z phase) in this example) Specify the home offset (–2147483647 to 2147483647 pulses). If the home offset is not required, specify “0”. 16.Pr** 32.Pr**30 31 32 33 34 35 36 37 3B 01Parameter number• Parameters related to this operationCaution1) If any of the set values of the parameters below is “0”, an operation trips due to homing error protection(error code No. 68) and stops according to an operation at alarm occurrence.• 16.Pr30 (Homing speed (high))• 16.Pr31 (Homing speed (low))• 16.Pr33 (Homing acceleration setting)• 16.Pr34 (Homing deceleration setting)
