DOK-ECODR3-SGP-03VRS**-WA01-EN-P
C801 Parameter default value erroneous (-> S-0-0021)
Cause:
During the execution of P-0-4094, C800 Command Base-parameter
load, a default value that has been stored in the drive was recognized as
incorrect. The related parameter is entered in the S-0-0021, IDN-list of
invalid op. data for comm. Ph. 2.

C802 Locked with password
The parameter S-0-0267, Password offers the possibility to set a write
protection for the drive parameters. The diagnostic message C705
Locked with password indicates, that the command P-0-4094, C800
Command Base-parameter load has been started, although the drive

D300 Command adjust commutation
A correctly adjusted commutation offset is mandatory for the operation of
synchronous motors. The "D3“ message indicates that the command has
been activated, that is used for determining the commutation offset.
Cause:
The commutation setting command has been activated.
See also the functional description: "Determining commutation offset"
D301 Drive not ready for commutation command
Meaning:
The drive must be in torque control mode when the "D3“ command is
started.
Cause:
Activate torque control and start the command again.

D302 Torque/Force too small to move
The command D3 Command adjust commutation has been started. To
perform this, the motor must move. But it doesn’t move.
Cause:
1. The torque is too small to overcome mechanical resistances (friction
or weight).
2. The motor is blocked mechanically.
3. Motor movement and encoder rotation direction are contradictory to
each other.
