MH300
12.1-11-56
11-69
Homing Control Time Out
Default: 60.0
Settings 0.0–6000.0 sec.
 Set the time limit for completing the homing process. When executing homing position control, a
fault occurs for the drive if positioning time exceeds Pr.11-69.

11-70
Homing Control First Step Speed
Default: 8.00
Settings 0.00–599.00 Hz

11-71
Homing Control Second Step Speed
Default: 2.00
Settings 0.00–599.00 Hz
 There are two steps of speed for the homing process:
CiA402 defines:
 The first-step speed is used to locate the switch signals (positive limit switch, negative limit
switch and ORG switch)
 The second-step speed is used to locate the reference point (Z-phase signal, the rising / falling
edge of the ORG switch signal)
 Considering the braking distance when the motor encounters the switch signal, do not use a too
fast first-step speed.
 To ensure the high repeatability of the reference point, use a low second-step speed.
 When executing homing control, the last rising speed refers to the setting of Pr.11-70.

11-72
Homing Control Acceleration / Deceleration Time
(0–Homing Control 1
st
Step Speed)
Default: 10.00
Settings 0.00–600.00 sec.
 This parameter is the first-step of acceleration / deceleration time from 0 Hz to Pr.11-70 when the
homing position control function is enabled.
 Acceleration / deceleration time in the process of homing refers to Pr.11-72 setting value.
