Appendix A: Parameter Reference List

Siemens Building Technologies, Inc. 121

P2185, P2187,

P2189

Upper torque threshold 1, 2, and 3

Min: 0.0 Def: 99999.0 Max: 99999.0

Level 2

Details:

Upper limit threshold value for comparing actual torque.

Note:

See P2182 (belt threshold frequency).

P2186, P2188,

P2190

Lower torque threshold 1, 2, and 3

Min: 0.0 Def: 0.0 Max: 99999.0

Level 2

Details:

Lower limit threshold value for comparing actual torque.

Note:

See P2182 (belt threshold frequency).

P2191 Belt failure speed tolerance

Min: 0.00 Def: 3.00 Max: 20.00

Level 2

Details:

P2191 defines the allowed speed variation bandwidth between the inverter frequency, and the speed reference from the

pulse train. When the speed of the driven machine varies by more than this amount, a trip or warning is given.

P2192 Time delay for belt failure

Min: 0 Def: 10 Max: 65

Level 2

Details:

P2192 defines a delay before warning/trip becomes active. It is used to eliminate events caused by transient conditions. It

is used for both methods of fault detection.

Bit11 Belt failure warning 0 NO, 1 YES

Bit12 Belt failure trip 0 NO, 1 YES

P2200[2] BI: Enable PID controller

Min: 0:0 Def: 0:0 Max: 4000:0

Level 2

Details:

PID mode Allows you to enable/disable the PID controller. Setting to 1 enables the PID closed-loop controller.

Index:

P2200[0] : IN000 (AUTO) 1st. Command data set (CDS) P2200[1] : IN001 (HAND) 2nd. Command data set (CDS)

Dependency:

Setting 1 automatically disables normal ramp times set in P1120 and P1121 and the normal frequency setpoints.

Following an OFF1 or OFF3 command, however, the inverter frequency will ramp down to zero using the ramp time set in

P1121 (P1135 for OFF3).

Note:

The PID setpoint source is selected using P2253. The PID setpoint and the PID feedback signal are interpreted as [%]

values (not [Hz]). The output of the PID controller is displayed as [%] and then normalized into [Hz] through P2000

(reference frequency) when PID is enabled.

In level 3, the PID controller source enable can also come from the digital inputs in settings 722.0 to 722.2 for DIN1 to DIN3

or from any other BiCo source.

The minimum and maximum motor frequencies (P1080 and P1082) as well as the skip frequencies (P1091 to P1094)

remain active on the inverter output. However, enabling skip frequencies with PID control can produce instabilities.
