148 Description of Parameters Honeywell
349 Torque limit, supervision value 34567 (2.3.15, 2.3.4.6, 2.3.2.6)
Set here the torque value to be supervised by parameter ID348.
Applications 3 and 4:
Torque supervision value can be reduced below the setpoint with external free analogue
input signal, see parameters ID361 and ID362.
350 Reference limit, supervision function 34567 (2.3.16, 2.3.4.7, 2.3.2.7)
0 = No supervision
1 = Low limit supervision
2 = High limit supervision
If the reference value falls below or exceeds the set limit (ID351), this function generates
a warning message via the digital output DO1 or via a relay output RO1 or RO2
1) depending on the settings of parameters ID312 to ID314 (applications 3,4,5) or
2) depending on to which output the supervision signal (par. ID449) is connected
(applications 6 and 7).
The supervised reference is the current active reference. It can be place A or B
reference depending on DIN6 input, or panel reference if the panel is the active control
place.
351 Reference limit, supervision value 34567 (2.3.17, 2.3.4.8, 2.3.2.8)
The frequency value to be supervised with the parameter ID350.
352 External brake-off delay 34567 (2.3.18, 2.3.4.9, 2.3.2.9)
353 External brake-on delay 34567 (2.3.19, 2.3.4.10, 2.3.2.10)
The function of the external brake can be timed to the start and stop control signals with
these parameters. See Figure 8-24 and chapter 9.1 on page 210.
The brake control signal can be programmed via the digital output DO1 or via one of the
relay outputs RO1 and RO2, see parameters ID312 to ID314 (applications 3,4,5) or
ID445 (applications 6 and 7).
