Commander S100 User Guide 45
6.2 Controlling the motor speed
In the Commander S100, up to four references can be configured at one time and the user can switch between these references using digital inputs
or by selecting a specific reference in Frequency Reference 1 to 4 Switch (P2.20). The references are configured in the parameters Frequency
Reference 1 Selector (P2.21) to Frequency Reference 4 Selector (P2.24) with the reference inputs shown in Table 6-1.
Table 6-1 Frequency references
Frequency Reference Configuration (P0.05) will set up the drive references and control terminal functions automatically and can be used to quickly
configure the drive for the most common applications.
The changes to the control connections and details on increasing and decreasing the frequency reference for the particular configuration can be
found below.
P0.05 = Local/Remote (1) Default
The primary frequency reference is a current input on analog input 1 where 4 mA = Minimum Frequency Limit (P0.01), and 20 mA = Maximum
Frequency Limit (P0.02). The secondary frequency reference is a voltage input on analog input 2 where 0 V = Minimum Frequency Limit (P0.01), and
10 V = Maximum Frequency Limit (P0.02). Switch between the two references using digital input 5.
Value Frequency Reference Description
0 None The frequency reference is fixed at the Minimum Frequency Limit (P2.01)
1 Preset 1 The frequency reference is defined by Preset Frequency 1 (P2.16)
2 Preset 2 The frequency reference is defined by Preset Frequency 2 (P2.17)
3 Preset 3 The frequency reference is defined by Preset Frequency 3 (P2.18)
4 Preset 4 The frequency reference is defined by Preset Frequency 4 (P2.19)
5 Analog 1 Percent The frequency reference is derived from T2 Analog Percentage 1 (P1.15)
6 Analog 2 Percent The frequency reference is derived from T4 Analog Percentage 2 (P1.16)
7 Frequency Input Percent The frequency reference is derived from T15 Frequency Input Percentage (P1.17)
8 Up / Down Percent The frequency reference is derived from Up/Down Percentage (P1.18)
9 PID Percent The frequency reference is derived from PID Percentage (P1.19)
