Table 7- 45 Parameters that are required to set the essential service mode
Parameter
Description
Setting the source for the essential service mode
p3880 = 722.3
ESM activation (here, via DI3, high-active)
Signal source for activating the essential service mode
722.x for high active, 723.x for low active
Additional parameters to set the essential service mode
p3881
ESM setpoint source, 0 … 4
p3882
ESM substitute setpoint source
Setpoint should the parameterized ESM setpoint be lost
p3883
ESM direction of rotation
Signal source for direction of rotation in the essential service mode, is not
evaluated when p3881 = 4
p3884
ESM setpoint technology controller
If p3884 is not connected up, then the technology controller uses the main
setpoint corresponding to p2251 = 0.
r3887
ESM: Number of activations and faults
Indicates how frequently ESM has been activated (index 0) and how many faults
occurred during ESM (index 1).
p3888
ESM: Reset the number of activations and faults
p3888 = 1 resets 3887[0] and 3887[1].
r3889
ESM status word
Faults, which are not ignored when operating in the essential service mode
