2. The drive automatically runs either upward or downward, depending on which has a
lighter duty, to execute safety landing.
3. When elevator starts running, it runs with either Pr.04-04 (Non-leveling Speed) or with
Pr.13-49 (EPS Running Frequency) first, depending on which has a slower speed. Then,
the elevator runs with Pr.04-05 (Leveling Speed) after encountering the leveling switch.
Finally, it automatically stops running after leveling.
4. After safety landing is finished and elevator has stopped for a while, MO function setting
9 (YUPS) is outputted to make emergency power stop supplying.
 UPS mode:
1. Set Pr.03-09 (UPS Designated Floor)=0, and MI function setting=67 (UPS).
2. The elevator must work with MI function setting 125 BALWG (Balanced switch) to
execute safety landing. The elevator executes downward safety landing when BALWG is
ON; executes upward safety landing when BALWG is OFF.
3. When elevator starts running, it runs with either Pr.04-04 (Non-leveling Speed) or with
Pr.13-49 (EPS Running Frequency) first, depending on which has a slower speed. Then,
the elevator runs with Pr.04-05 (Leveling Speed) after encountering the leveling switch.
Finally, it automatically stops running after leveling.
4. After safety landing is finished and elevator has stopped for a while, MO function setting
9 (YUPS) is outputted to make emergency power stop supplying.
 UPS designated floor mode:
1. This mode is activated once Pr.03-09 (UPS Designed Floor)≠0, regardless of MI
function setting = 67 (UPS) or 54 (EPS).
2. As long as MI function setting UPS or EPS is activated, the elevator automatically runs
with high speed to designated floor and stops. After stopping a while, MO function
setting 9 (YUPS) is outputted to make emergency power stop supplying.
 Set the following parameters only for EPS or UPS mode: Pr.13-48 (Voltage of Emergency Power),
Pr.13-51 (Power Generation Direction Search Time), and Pr.13-52 (Power Capacity of
Emergency Power).
STO Latch Selection
Settings 0000h–0007h
 Sets this value to 0003h.
Zero Speed Activation Time
Settings 0.1–60.0 sec.
 Sets the time that motor keeps at zero speed when activating the drive.
Zero Speed Stopping Time
Settings 0.0–3.0 sec.
 Sets the time that motor keeps at zero speed when motor decelerates to zero.
Time for Decreasing Torque at Stop
Settings 0.000–5.000 sec.
 When the elevator is stopped and the mechanical brake is engaged, the drive stops output. At
the same time, it produces noise from the reacting force between the motor and the mechanical
brake. Use this parameter to decrease this reacting force and lower the noise.
 Sets the time when torque decreases from 300% to 0%.
