 Using Inverter for Elevating Machines
If using an Inverter with an elevator, take safety mea-
sures on the elevator to prevent the elevator from drop-
ping.
Failure to observe this caution may result in injury.
When using the VS-606V7 for elevating machines such as elevators and
cranes, make sure that the brake holds and observe the following pre-
cautions for safe operation.
 Brake ON/OFF Sequence
• For the holding brake’s ON/OFF sequence, use the following Inverter
output signals according to the set control mode.
Do not use “Running (Set value: 1)” for the holding brake’s
ON/OFF interlock signal.
* 1. For Vector control (n002=1), use the same brake ON/OFF sequence with
the same signals as for V/f control.
* 2. Shows the setting when a multi-function photocoupler output terminal
(P1-PC) is used.
* 3. Usually, make the following settings for the frequency detection (n095):
For V/f control: Motor rated slip frequency +1 Hz
For Vector control: 2.5 Hz to 3.0 Hz
If the set value is too low, the motor torque is insufficient and the load
may shift when the brake is applied. Be sure to set n095 to a value larger
than that of the Minimum Output Frequency (n016) and larger than that
of the braker releasing width shown in the following figure. If the set
value is too large, the motor may not run smoothly when it starts running.
