Chapter 12 Descriptions of Parameter Settings | IED-S
Drive Output Delay Time
Settings 0.010–0.500 sec.
 Sets the time the drive starts to output current after operation contactor and STO are activated.
See speed control timing diagrams in this parameter group for reference.
Operation Contactor Off Delay Time
Settings 0.010–1.667 sec.
 Sets the time the operation contactor is to be deactivated after the drive stops outputting current
since elevator stops. See speed control timing diagrams in this parameter group for reference.
Voltage of Emergency Power
Settings 24.0–375.0 V
EPS Running Frequency
Settings 0.00–655.35 Hz
 If emergency power is supplied by DC, set the frequency based on DC voltage. If emergency
power is supplied by AC, set the frequency by multiplying AC voltage by 1.41.
Power Generation Direction Search Time
Settings 0.0–5.0 sec.
Power Capacity of Emergency Power
Settings 0.0–100.0 kVA
 Set according to actual emergency power capacity.
 When using emergency power (EPS), you must set the parameter to the required power capacity
for the emergency power, and then the drive calculates the acceptable elevator speed (Pr.13-49)
with the following equation.

When the Frequency command > fEPS, the running frequency of emergency power (EPS) is fEPS.
When the Frequency command ≤ fEPS, the running frequency of emergency power (EPS) is set according
to the current Frequency command.
 Using emergency power during power-off for automatic safety landing for IED-S:
There are three modes of emergency power: Pr.03-09 (UPS Designated Floor), MI function
setting=54 (EPS), and MI function setting=67 (UPS). The elevator can execute inspection
operation in either of these three modes.
 EPS mode:
1. Set Pr.03-09 (UPS Designated Floor)=0, and MI function setting=54 (EPS).
