Step 1. High Speed Near Home Search
The step 1 outputs the drive pulse until near home signal (nSTOP0) becomes active with high speed near
home search speed set in Parameter tab and specified direction.
To execute the high speed near home search operation, the home search in high speed is configured as
higher value than the start speed�
If the near home signal (nSTOP0) is activated during high speed near home search with the accel/decel
speed drive, the drive stops immediately�
Caution
Irregular operation
①
Near Home Signal (nSTOP0) is activated before starting the step 1. → Run the step 2.
②
Limit signal of the detected direction is activated before starting the step 1. → Run the step 2.
③
Limit signal of the detected direction is activated in operating. → Stop the drive and runt the step 2.

Step 2. Low Speed Home Search
The step 2 outputs the drive pulse to the Home Search Low Speed set in Parameter tab and the specified
direction until the home signal (nSTOP1) is activated.
To execute the low speed search operation, the home search in low speed is configured as lower value than
the start speed�
If the home signal (nSTOP1) is activated to the constant speed drive, the drive stops immediately.
Caution
Irregular operation
①
The home signal (nSTOP1) is activated before starting the step 2 → Move in the opposite direction of the
specified detection searching home in low speed until the home signal (nSTOP1) is deactivated.
When the home signal (nSTOP1) is deactivated, the step 2 starts.
②
The limit signal of the detected direction is activated before starting the step 2 → Move in the opposite
direction of the specified detection searching home in low speed until the home signal (nSTOP1) is
activated. If the home signal (nSTOP1) is activated, PMC-1HS/PMC-2HS moves in the opposite direction
of the specified detection searching home in low speed until the home signal (nSTOP1) is deactivated.
When the home signal (nSTOP1) is deactivated, the step 2 starts.
③
The limit signal of the detected direction is activated in use. → Stop the drive and perform the same
operation with
