HM[N] (Index)

Value

Description

In UM=2, 3, 4, 5: Stop immediately using the SD
deceleration value. In torque mode (UM=1), do nothing.

Set digital output, equivalent to OP=HM[6].

4
After-event
behavior.
Defined as the
time in which
HM[1]
decreases to 0.

2 Do

nothing.

Absolute setting of position counter: PX=HM[2].

Relative setting of position counter:
PX=PX (at event) -HM[2]

5
What to set for
PX during event

2 Do

nothing.

6
Output value

Digital output value if HM[4]=1.
Only outputs defined as general output are affected.

7
PX captured
value

The captured value of PX (read only). The position value
is captured before PX is changed according to HM[5].

8
PY captured
value

The captured value of PY (read only). The position value
is captured at the next controller sampling time and
therefore may be inaccurate to (4*VX*TS*10

-6

) counts.

Notes:

SimplIQ for Steppers drives have a different number of digital inputs. The value

of HM[3] may differ according to that. Please consult the drive’s Installation
Guide for details.

HM[2] - HM[6] can be changed during the home search procedure. The

activation of the parameters is considered upon reception of the next HM[1]=1
(or higher).

If HM[2] is set to a value beyond XM[1] and XM[2], the actual main position will

not be updated when homing is complete.

Each homing event is attached to a predefined functionality (FLS, General

Purpose, Home and so on). If the corresponding input is not defined first, the
homing procedure may never end. Refer to the

IL[N]

command.

The homing and capture procedures can be carried out in any unit mode (UM=1,

2, 3, 4, 5) and reference mode (RM=0, 1).

In external reference mode (RM=1), when HM[4]=0, the software portion of the

reference is stopped, while the external portion is not. In such cases, the motor
continues to move according to the analog reference.
