Code Description
4013 PID SLEEP DELAY
Time delay for the sleep function, see Figure 23. If the ACS 160 output frequency is below a set level
(parameter 4014
Alarm 28 is displayed when PID sleep is active.
4014 PID SLEEP LEVEL
Level for activation of sleep function, see Figure 23. When the ACS 160 output frequency falls below the
sleep level, the sleep delay counter is started. When the ACS 160 output frequency rises above the sleep
level, the sleep delay counter is reset.
4015 WAKE-UP LEVEL
Level for deactivation of sleep function. This parameter sets a process actual value limit for the sleep
function (see Figure 23). The limit floats with the process reference.
Non-inverted error value
Applied wake-up level is according to the following formula:
Limit = parameter 1107 +
parameter 4015 * (set point - parameter 1107) /
(parameter 1108 - parameter 1107)
When the actual value is less than or equal to this value, the sleep function is deactivated. See Figure 24
and Figure 26.
Inverted error value
Applied wake-up level is according to the following formula:
Limit = parameter 1108 +
parameter 4015 * (parameter 1108 - setpoint) /
(parameter 1108 - parameter 1107)
When the actual value is higher than or equal to this value, the sleep function is deactivated. See Figure 25
and Figure 27.
4016 PID PARAM SET
PID parameter set selection. When set 1 is selected, parameters 4001-4012 and 4019-4020 are used.
When set 2 is selected, parameters 4101-4112 and 4119-4120 are used.
1...5 = DI1...DI5
PID parameter set is selected through a digital input (DI1...DI5). Parameter set 1 is used when the digital
input is not active. Parameter set 2 is used when the digital input is active.
6 = 1
SET
PID parameter set 1 is active.
7 = 2
