Code Description
8216 HOMING MODE
Homing mode is possible only when external control locations EXT2 is selected.
0 =
NOT SEL
Homing is not used.
1 - 3 = reserved
4 = 1
HOMING
Homing frequency reference is set with parameter 1207
digital input 3 (DI3):
• direction is forward when DI3 is inactive.
• direction is reverse when DI3 is active.
Home position is set to position counter when DI3 state changes. After this homing speed reference is
internally forced to zero. Load decelerates from homing frequency to zero. Positioning is enabled when stop
command is given.
5 = 2
HOMING
Like 1 with the following difference:
HOMING
• direction is reverse when DI3 is inactive
• direction is forward when DI3 is active
6 = 3
HOMING
Like 4 and
HOMING
• direction is forward when AI1 = 0...4 V (0...8 mA)
• direction is reverse when AI1 = 6...10 V (12...20 mA).
Note! When value 4 or 5 is selected, the drive will perform homing operation when it is powered up and it
receives the first start command. External control place EXT 2 must be selected. After the homing operation
is completed the drive will go to positioning mode as set by parameter 8215
8217 AUX POS CMD
Auxiliary positioning mode commands selection.
0 =
NOT SEL
1 = 2
DI
Digital input 2 (DI2) is used to give auxiliary positioning start/stop commands. This command does not start
or stop the ACS 160 modulation. During homing this command acts only as start enable.
2 = 0
STOP HZ
Positioning frequency reference is set to 0 Hz when positioning target window has been reached.
3 =
STOP MODUL
Modulation is stopped when positioning target window has been reached.
4 =
EXT FREQ
Enables external frequency reference use at positioning mode 9. Frequency reference is selected with
parameter 1106
Allowed selections: parameter 1106 (
External frequency reference update can be controlled with digital input DI2:
• DI2 is inactive, frequency is sampled at turning points.
• DI2 is active, frequency reference is sampled continuously.
8218 SLOPE GAIN 1
Frequency reference deceleration slope control. Values above 1000 delays the beginning of the deceleration
ramp and make target position approach faster. Values below 1000 increase the effective deceleration time
and make target position approach slower.
8220 SPEED GAIN 1
Gain factor of positioning speed control during deceleration. Higher value means higher speed.
8221 T WINDOW LO
8222 T WINDOW HI
Target position window limit, refer to example on page 100.
Operation: When the actual value of position is inside the target area (target ref+- target window), the relay
output is activated, if parameters 1401
The relay is deactivated when next position start command is given.
