Note:
To perform a positioning run without a loop, in addition to setting the release
(bit 4 in the command byte), you must also set bit 6 (“Run without loop”) or ISDU
124 (“Loop length”) must have the value 0.
Note:
In this mode any backlash that might produced by the driven spindle is NOT
eliminated. For models with an integrated auxiliary gearbox, in this case also the
internal gear backlash does influence the positioning accuracy.
4.2.3
Manual run
The drive can be operated manually (so-
called “Manual run”). This helps to simplify
commissioning.
- Transfer manual run
Command byte = 0x11 and/or 0x12
Drive begins run
- End manual run by withdrawing manual run command
transmit command byte = 0x10
or
Removal of the release
transmit command byte = 0x00
Note:
If a positioning run is required during an active manual run, the drive must
be stopped (reset the release bit). The positioning can be started when the drive is
at a standstill (command byte = 0x14 and required target value).
4.3
Velocity, acceleration and deceleration
Start-up reference loops and manual runs are performed at the maximum velocity from
ISDU 138.
Positioning runs are performed at the maximum velocity from ISDU 142.
For all runs, the maximum acceleration from ISDU 139 and the maximum deceleration from
ISDU 141 apply.
Note:
If during a run the release bit in the command byte is cleared or the target
position is approached, the deceleration is carried out with the parameter
“deceleration” (ISDU 141). If the speed is increased or decreased during a run, the
parameter “acceleration” is used (ISDU 139).
4.4
Maximum start-up and operating current
The maximum start-up current can be set via ISDU 147, the maximum operating current can
be set via ISDU 148.
The start-up current is active after each run begins for the period defined in ISDU 155.
