Unit Description
p100 0 = FBLOCK + Bus 
1 = FBLOCK + relay 
0 — Default command mode:
For the ATD420W, ATD430W control units the com‐
mand input via the bus system is activated in the de‐
fault setting -> parameter p100 = 0. This means that 
the FBLOCK drive orders can only be executed in the 
drive state "S4: Z_MODE" (see Figure 4-4 State graph 
control unit (Page 163)).
For the ATD401W control unit with relay module, no 
command mode is possible via the bus system. For 
this control unit variant, parameter p100 = 1 must 
always be set. Otherwise, the control unit cannot be 
controlled via the digital inputs.
r200 1 … 65535
0 = Checksum invalid
— — Checksum for the default parameters (see Checksum 
parameters (as of V1.12) (Page 77))
r201 1 … 65535
0 = Checksum invalid
— — Checksum for the learn run parameters (see Check‐
sum parameters (as of V1.12) (Page 77))
r202 0 … 65535 — — Change counter for the default parameters 
(see Checksum parameters (as of V1.12) (Page 77))
r203 0 … 65535 — — Firmware version 
The version is output as "MajorVer*100 + MinorVer". 
e. g. rmware version "1.13.1234" is output as "113".
r204 0 = Checksum invalid
1 = Checksum valid
— — Validity of the checksum for the default parameters 
r200, r201.
p2080 0 … 65535 FFFF (hex) — DCMD masking eldbus
Each bit in the mask lters the corresponding bit in 
TSW1:
0: CMD bit is not allowed to pass
1: CMD bit is allowed to pass
p2081 0 … 65535 FFFF (hex) — DCMD masking FBLOCK
Each bit in the mask lters the corresponding bit in 
TSW1:
0: CMD bit is not allowed to pass
1: CMD bit is allowed to pass
