Note
Loss of warranty for an converter operated in the essential service mode
Should essential service mode apply, the customer can no longer lodge any claims for
warranty.
The essential service mode is an exceptional state, and is not suitable for continuous
operation.
The essential service mode can have the following effects:
• Exceptionally high temperatures inside and outside the converter
• Open fire inside and outside the converter
• Emissions of light, noise, particles, gases.
The converter logs the essential service mode, and the faults that occur while in essential
service mode in a password-protected memory. This data is only accessible for the service
and repair organization.
Note
Emergency operation and Safety Integrated
The use of the essential service mode with the simultaneous use of a Safety Integrated
function can lead to an undesirable state of the essential service mode.
The background is that the motor must continue to run during essential service mode as long
as possible and also must not be shut down by a Safety Integrated function.
• Do not use a Safety Integrated function simultaneously with the essential service mode.
Activating essential service mode
Essential service mode is activated through a continuous signal to the digital input, which is
set as a signal source via p3880.
Only the digital inputs on the Control Unit are permitted as signal sources:
● r0722.x (high active)
● r0723.x (low active)
x = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 20, 21
Note
Emergency operation is not fully functional until one of the following requirements is met:
• p3880 is wired offline; a POWER ON of the CU must then be performed after the
