Using Inverters For Elevating Machines - YASKAWA varispeed G7 CIMR-G7B series Instruction Manual

Sequence Circuit Configuration
The brake ON/OFF sequence circuit configuration is shown below.
Inverter (Varispeed G7)
UP
S1
(Forward run)
DOWN
S2
(Reverse run)
HIGH/LOW
S6
(Multi-step speed reference 2)
SC
Note Design the sequence so that the holding brake contact is open when the sequence operation conditions are satisfied and the contact between M1 and M2
is closed (ON).
Make sure that the holding brake contact is closed when the emergency stop signal or Inverter fault contact output signal is ON.
