4.9 Drag error correction
With Par. 48 the drag error correction can be enabled. With this feature enabled, the
drive will raise or lower the target speed proportional to the drag error by the
configured value. The drive attempts under consideration of the configured maximum
current to compensate the drag error which has developped by controlling the target
speed to a value which lays slightly above or below the specified value of the target
speed (Par. 53).
By setting Par. 48 to 0 the drag error correction can be disabled.
Drag error monitoring and correction take effect always except during a braking
operation when approaching a target position or when aborting a positioning. The
actual target speed when accelerating is determined by the actual speed at the
beginning of the positioning and the acceleration setting (Par. 58).
4.10
Response at power up, at “IOPS = BAD” and at connection timeout
Behaviour at power-up (apply power to the control unit):
The behaviour is defined by bits 3-2 of Par. 93. There are basically two types of
behaviour:
1) The drive enters the holding state.
This behaviour is enabled if bits 3-
2 of Par. 93 (“configuration for connection
timeout”) is set to 0x00.
2) The drive moves to the safety position.
This behaviour is enabled if bits 3-
2 of Par. 93 (“configuration for connection
timeout”) is set to a value > 0:
0x01: safe position run after 15 sec
0x02: safe position run after 30 sec
0x03: safe position run after 60 sec
The safety position is the position which is defined with Par. 94.
The run to the safety position starts after the specified time has elapsed since the
power-up of the unit (i.e. after 15, 30 or 60 sec.).
The safe position run can also be started repeatedly in case of failure, this is
configured by Pa
r. 95 (“repetition time for safe position run”).
If the connection to the IO controller is established during the run to the safety
position, the drive aborts the safe position run and enters the holding state.
From
now on it’s possible to send run commands.
