(Overspeed Test Source)    
This switch determines the source of the 
overspeed test.  Operation of the overspeed test 
function is specified by the OVRSPEED MULT 
(A1) parameter.  Regardless of the setting of 
this parameter, the user can call for the 
overspeed test via the Digital Operator.

Y Y 

(Brake Pick Source)   
If the BRAKE PICK SRC (C1) is set to 
INTERNAL, the Drive will attempt to pick (lift) 
the brake when magnetizing current has been 
developed in the motor. 

−  internal 

−  serial 

Y Y 

(Brake Pick Confirm)   
If this switch is set to EXTERNAL TB, the Drive 
will wait for brake pick confirmation before 
releasing the speed reference. When set to 
EXTERNAL TB, the MECH BRK PICK signal on 
TB1 must also be selected.

(Brake Hold Source)   
If set to internal, the drive will command the 
mechanical brake to hold mode after 
confirmation of brake picked exists.

(Ramp Stop Select) 

  

This parameter allows the selection of the 
Torque Ramp Down Stop function.  This 
function is used to gradually remove the torque 
command after the elevator has stopped and the 
mechanical brake has been set.  This prevents a 
shock and possible ‘bump’ felt in the elevator 
from the torque signal going to zero too quickly.  
For more information, see Ramp Stop Select on 
page 60.

(Ramp Down Enable Source) 

  

If RUN LOGIC is selected, the user can remove 
the run command and the drive will delay in 
dropping the run command until torque ramp 
down stop function is complete.   
If EXTERNAL TB or SERIAL is selected, the 
user must keep the run command while allowing 
the Torque Ramp Down Stop function to be 
completed.

(Brake Pick Fault Enable)   
When this parameter is set to ENABLE, the 
brake pick command and confirmation must 
match within the specified time determined by 
the BRK PICK TIME (A1) parameter or a brake 
pick fault is declared.   

−  disable

(Brake Hold Fault Enable)   
When this parameter is set to ENABLE, the 
brake hold command and confirmation must 
match within the specified time determined by 
the BRK HOLD TIME (A1) parameter or a brake 
hold fault is declared.
