Actual signals and parameters 229 All parameters No. Name/Value Description Def/FbEq TIMED FUNC 3 See selection TIMED FUNC 1. 11 TIMED FUNC 4 See selection TIMED FUNC 1. 12 DI1(INV) Inverted digital input DI1. 0 = active, 1 = inactive. -1 DI2(INV) See selection DI1(INV). -2 DI3(INV) See selection DI1(INV). -3 DI4(INV) See selection DI1(INV). -4 DI5(INV) See selection DI1(INV). -5 Defines the offset for the external PID controller output. When PID controller is activated, controller output starts from the offset value. When PID controller is deactivated, controller output is reset to the offset value. Parameter 4230 TRIM MODE must be set to NOT SEL. 0.0% 4229 OFFSET 0.0…100.0% 4230 TRIM MODE NOT SEL Value in percent 1 = 0.1% Activates the trim function and selects between the direct and proportional trimming. With trimming it is possible to combine a corrective factor to the drive reference. See section Reference trimming on page 119. NOT SEL No trim function selected 0 PROPORTION Active. The trimming factor is proportional to the rpm/Hz AL reference before trimming (REF1). 1 DIRECT 2 4231 TRIM SCALE Active. The trimming factor is relative to a fixed maximum limit used in the reference control loop (maximum speed, frequency or torque). Defines the multiplier for the trimming function. See section 0.0% Reference trimming on page 119. -100.0…100.0% Multiplier 1 = 0.1% 4232 CORRECTION Selects the trim reference. See section Reference trimming PID2REF SRC on page 119. PID2REF PID2OUTPUT PID2 reference selected by parameter 4210 (ie signal 0129 1 PID 2 SETPNT value) PID2 output, ie signal 0127 PID 2 OUTPUT value 2 44 PUMP PROTECTION Set-up of pump protection. 4401 INLET PROT CTRL Enables, and selects the mode of, the primary supervision of pump/fan inlet pressure. Note: Inlet protection is active only when the active reference is PID. NOT SEL NOT SEL Primary inlet pressure supervision not used 0 ALARM Detection of low inlet pressure generates an alarm on the control panel display. 1 Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: [email protected]
