A22
Global, OFF
r=1, w=2
Brake resistor P: Power of the brake resistor used. A22=0 means the brake chopper is
deactivated. Only values in 10 W increments can be entered.
Value range in W: 0 ... 150 ... 3200
Fieldbus: 1LSB=1W; Type: I16; (raw value:1LSB=10·W); USS-Adr: 01 05 80 00 hex

A23
Global, OFF
r=1, w=2
Brake resistor thermal: Thermal time constant of the brake resistor.
Value range in s: 1 ... 46 ... 2000
Fieldbus: 1LSB=1s; Type: I16; USS-Adr: 01 05 C0 00 hex

A29
Global
r=2, w=2
Fault quick-stop: If the parameter is inactive, the power section is turned off when a fault
occurs. The motor coasts down. If the parameter is active, a quick stop is executed when a fault
occurs if the event permits (see event list).
0: inactive; Coast down (disable power section immediately).
1: active; Execute quick stop.
Fieldbus: 1LSB=1; Type: U8; USS-Adr: 01 07 40 00 hex

A34
Global
r=2, w=2
Auto-start: When A34=1 is set, the device state "switch-on disable" to "ready for switch-on" is
exited both during first startup and after a fault reset although the enable is active. With fault reset
via enable, this causes an immediately restart! A34 is only supported with standard device state
machines and not with DSP402 device state machine.
WARNING
Before activation of auto-start with A34=1, check to determine whether an automatic restart is
allowed (for safety reasons). Only use auto-start under consideration of the standards and
regulations which are applicable to the plant or machine.
0: inactive; After power on, a change of the enable from L-level to H-level is necessary to enable
the drive (→ message "1:switch-on disable"). This prevents an undesired startup of the motor
(machine safety).
1: active; If auto-start is active, the drive can start running immediately after power on and existing
enable.

A35
Global, OFF
r=2, w=2
Low voltage limit: When the inverter is enabled and the DC link voltage goes lower than the
value set here, the inverter triggers the indication of the event "46:Low voltage." A35 should be
approximately 85% of the applied power voltage so that the possible failure of a network phase is
absorbed.
Value range in V: 180.0 ... 350,0 ... 570.0
Fieldbus: 1LSB=0,1V; Type: I16; USS-Adr: 01 08 C0 00 hex

A36
Global, OFF
r=2, w=2
Mains voltage: Maximum voltage which the inverter provides to the motor. Usually the power
(mains) voltage. Starting with this voltage, the motor runs in the weak field range.
Value range in V: 220 ... 400 ... 480
Fieldbus: 1LSB=1V; Type: I16; (raw value:32767 = 2317 V); USS-Adr: 01 09 00 00 hex

Reset memorized values & start: The six different memorized values E33 to E38 (max.
current, max. temperature, and so on) are reset.
