S- Ramps are used to smooth the starting and stopping behaviour of the drive, refer to the diagram in section 13.1 for further
information on the operation of the S-Ramps.
P3-06
Output Contactor Closing Time/Run command delay time
0.00
5.0
0.2
s
Sets a delay time between the enable signal being applied to the Optidrive P2 Elevator drive and energising of the motor. This
prevents over current trips which may be caused when a contactor is installed between the Optidrive P2 Elevator drive and the motor.
The contactor can optionally be controlled by the drive using Output Relay 1.
P3-07
Brake Release time
0.0

0.50
s
Sets the delay time, following the contactor Delay time (P3-06) in which the motor brake will be released (Relay 2) and the drive
output frequency ramps up.
P3-08
Brake Apply Delay

2.00
0.20
s
Sets the delay time allowed for the motor brake to apply when stopping. (Motor brake control method 2 in section 6.12.2
P3-09
Brake Apply Speed
0.0
P1-01
0.0
Hz
Sets the speed at which the drive will signal the motor brake to apply. This speed must not be greater than the levelling &
maintenance speeds.

Zero Speed Holding Time on disable
0.0
60.0
0.2
s
Sets the time for which the drive will hold the motor at zero speed prior to the output being disabled to allow the motor brake to
engage.

For software protection of the connected brake resistor, enter the rated power and resistance of the resistor into the relevant
parameters. The drive will then monitor the brake resistor to ensure that it does not operate outside of its designed limits.
Where an external thermal protection device is fitted, and software protection is not required. Setting parameter P3-14 to zero will
disable the software protection feature.

P3-15, P3-16 and P3-17 are used internally by the drive to provide elevator speed in user units as per section 9.7
Note: P1-10 must also be programmed for elevator speed in user units to operate.
P3-18
Motor Connected Check
0.0
100.00
15
%
At e
ach start, the drive injects a current pulse of this magnitude (% of motor rated current) to confirm that the motor is connected.
The default value rarely requires adjustment, the drive will trip “OUT-Ph” or “OUT-F” (Size 2) if the drive detects the motor is not
connected. See section 14.3 for more details.
P3-19
Torque Reduction during stopping
0.0
100
10.0
%
This parameter helps in reducing the noise in the lift car when the motor brake is closed due to the removal of current.
Increasing this value reduces audible noise, setting too high can result in reduced torque and rollback during stopping.
