(Tach Filter Bandwidth) 

 

Breakpoint of 

tachometer / encoder feedback signal. 

Y N 

(Tach Rate Gain) 

 

Used to help reduce the 

effects of rope resonance.  It should be 
adjusted only after the INERTIA and 
RESPONSE have been set correctly.   

Y N 

(Speed Phase Margin) 

 

This parameter 

sets the phase margin of the speed 
regulator assuming a pure inertial load.  
This parameter is only in affect if SPEED 
REG TYPE (C1) is set to PI REG. See 
INNER LOOP XOVER (A1) if using ELEV 
SPD REG. 

Y N 

(Ramped Stop Time) 

 

This parameter is 

used only by the torque ramp down 
function during a stop and sets the time to 
decrease motor torque from rated torque 
to zero.  After the elevator comes to a halt 
at a landing the brake is applied and the 
drive is told to turn off.  However, 
components of the mechanical brake must 
‘set’ ever so slightly in order to generate 
enough torque to hold the car.  This small 
movement can cause a significant ‘bump’ 
if the transfer of torque occurs too quickly.  
This effect is essentially eliminated by the 
Torque Ramp Down function.  
The Ramped Stop Select function is 
enabled at (RAMPED STOP SEL(C1)).  
The Ramped Stop Time Parameter 
determines the rate of motor torque decay 
with ramped stop enabled.  RAMPED 
STOP TIME(A1) determines the amount of 
time it would take for the drive to ramp 
from rated torque to zero torque.  The 
actual time for torque decay to occur on a 
typical stop will depend on the actual 
amount of torque required to hold the car. 

Y N 

(Contactor Fault Time) 

 

Determines 

allowable time for motor contactor 
feedback to be out of sync with 
commanded state before a CONTACTOR 
FLT occurs. 

Y N 

(Brake Pick Time) 

 

If BRAKE PICK CNFM 

is set to INTERNAL TIME this parameter 
sets the internal time the drive waits until it 
assumes the brake has been picked.  If 
BRAKE PICK CNFM is set to EXTERNAL 
TB, this parameter sets the time the drive 
waits until it receives a brake pick 
confirmation or a BRK PICK FLT will be 
declared. 

Y N 

(Brake Hold Time) 

 

Determines the time 

the drive will wait until a BRK HOLD FLT is 
declared if a logic input is set to MECH 
BRK HOLD 

Y N
