This is the minimum time that must be elapsed since a drive is disconnected from the AC Input before an operator may
service parts inside the drive to avoid electric shock hazard.
Condition:
These values consider a turn off for a drive supplied at 480Vac +10%, without any option, ( the charge
for the switching supply is the regulation card, the keypad and the 24Vdc fans "if mounted").
The drive is disabled. This represents the worst case condition.
AGy -L is a series of dedicated drives used to control lift asynchronous motors ranging from 4.0 to 200 kW.
Thanks to the special lift application software, it is best used in case of plant modernization and, in general, in all open loop
applications up to 1 m/s and higher in all closed loop applications, by using EXP-ENC-AGy option.
The easy and adaptable programming procedure can be managed via the alphanumeric keyboard or via the PC configurator
and it allows the drive fast commissioning.
Available options on demand:
- External EMC input filters
- External Input / Output chokes
- External braking resistors (connected between terminals C and BR1)
- Multilingual programming keypad complete with alphanumeric display: KBG-LCD-L (IT-ENG) (cod. S504K)
- Remote keypad kit
- E2PROM PRG-KEY key (cod. S6F38)
- I/O expansion card: EXP-D6A1R1-AGy (cod. S524L)
- 120 Vac digital input interface card: EXP-D8-120 (cod. S520L)
- Profibus interface card: SBI-PDP-AGy (cod. S5H28)
- Emergency Module MW22.
