F07599 (A) Encoder 1: Adjustment not possible
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The maximum encoder value times the factor to convert the absolute position (r0483 and/or r2723) from increments
to length units (LU) has exceeded the value range (-2147483648 ... 2147483647) for displaying the position actual
value.
Remedy: If the value for the maximum possible absolute position (LU) is greater than 4294967296, then it is not possible to
make an adjustment due to an overflow.
For rotary encoders, the maximum possible absolute position (LU) is calculated as follows:
1. Motor encoder:
p2506 * p2505 / p2504
p2506 * p2505 * p0421 / p2504 for multiturn encoders
2. Direct encoder:
p2506
p2506 * p0421 for multiturn encoders
F07600 (A) Encoder 2: Adjustment not possible
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The maximum encoder value times the factor to convert the absolute position (r0483 and/or r2723) from increments
to length units (LU) has exceeded the value range (-2147483648 ... 2147483647) for displaying the position actual
value.
Remedy: If the value for the maximum possible absolute position (LU) is greater than 4294967296, then it is not possible to
make an adjustment due to an overflow.
For rotary encoders, the maximum possible absolute position (LU) is calculated as follows:
1. Motor encoder:
p2506 * p2505 / p2504
p2506 * p2505 * p0421 / p2504 for multiturn encoders
2. Direct encoder:
p2506
p2506 * p0421 for multiturn encoders
F07800 Drive: No power unit present
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The power unit parameters cannot be read or no parameters are stored in the power unit.
It is possible that the DRIVE-CLiQ cable between the Control Unit and power unit is interrupted or defective.
Note:
This fault also occurs if an incorrect topology was selected in the commissioning software and this parameterization
is then downloaded to the Control Unit.
See also: r0200 (Power unit code number actual)
Remedy: - carry out a POWER ON (power off/on) for all components.
- check the DRIVE-CLiQ cable between the Control Unit and power unit.
- Check the power unit and replace if necessary.
- check the Control Unit, and if required replace it.
- after correcting the topology, the parameters must be again downloaded using the commissioning software.
F07801 Drive: Motor overcurrent
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The permissible motor limit current was exceeded.
- effective current limit set too low.
- current controller not correctly set.
- U/f operation: Up ramp was set too short or the load is too high.
- U/f operation: Short-circuit in the motor cable or ground fault.
- U/f operation: Motor current does not match current of power unit.
- Switch to rotating motor without flying restart function (p1200).
Note:
Limit current = 2 x minimum (p0640, 4 x p0305 x p0306) >= 2 x p0305 x p0306
