ABB ACS850 - Maintenance

224 Parameters
42.14 Extend run time Defines an extended run time for the brake control function at
stop. During the delay, the motor is kept magnetized
(modulating) and ready for an immediate restart.
0.0 s = Normal stop routine of the brake control function: The
motor magnetization (modulation) is switched off after the
brake close delay has passed.
0.1…3600.0 s = Extended stop routine of the brake control
function: The motor magnetization (modulation) is switched
off after the brake close delay and the extended run time have
passed. During the extended run time, a zero torque
reference is applied, and the motor is ready for an immediate
restart.
0.0 … 3600.0 s Extended run time. 100 = 1 s

Maintenance counter configuration. See also section
Maintenance counters on page 84.
44.01 Ontime1 func Configures on-time counter 1. This counter runs whenever
the signal selected by parameter 44.02 Ontime1 src is on.
After the limit set by parameter 44.03 Ontime1 limit is
reached, an alarm specified by parameter 44.04 Ontime1 alm
sel is given, and the counter reset.
The current value of the counter is readable from parameter
04.09 Counter ontime1. Bit 0 of 06.15 Counter status
indicates that the count has exceeded the limit.
44.02 Ontime1 src Selects the signal to be monitored by on-time counter 1. See
parameter 44.01 Ontime1 func.

Bit Function
0 Counter mode
0 = Loop: If alarm is enabled by bit 1, the alarm stays active only for 10 seconds.
1 = Saturate: If alarm is enabled by bit 1, the alarm stays active until reset.
1 Alarm ena (Alarm enable)
0 = Disable: No alarm is given when limit is reached.
1 = Enable: Alarm is given when limit is reached.
