4-24
Terminals 13 and 14 -- S1/4SP
Terminals 15 and 14 -- S2/4SP
Switch SW2 on the Control Board is factory set to 4SP. When set to 4SP,
two external switches may be connected to the drive as shown in Figure
4-3. In addition to the standard accel and decel rates set by Parameters 1
and 2, these switches may then be used to select;
–– Three additional accel rates
–– Four preset speeds
As programmed by Parameters 19, 29-31 and 36-41.
Terminals 13 and 11 -- S1/8SP
Terminals 14 and 11 -- S2/8SP
Terminals 15 and 11 -- S3/8SP
When switch SW2 on the Control Board is set to 8SP, a total of three
external switches may be connected to the drive as shown in Figure 4-3. In
addition to the standard accel and decel rates set by Parameters 1 and 2,
these switches may then be used to select three additional accel rates, three
additional decel rates, and seven preset speeds, as programmed by
Parameters 19-20 and 29-41.
Important: If parameter 20 is set to 1, switch S1 and S2 will select the
four preset speeds defined by Parameters 29-31. Switch S3 is reserved for
remotely setting a drive fault.
Terminals 16 and 17
Auxiliary Interlock
These factory jumpered terminals are used to install an auxiliary external
interlock when the jumper is removed. The interlock contact must be
closed to allow the drive to operate. The contact must be open for a
minimum of 100mS to sense an auxiliary fault. Parameter 21 will allow an
open contact to generate either:
A no-fault coast-to-stop sequence displaying AS –– Auxiliary Stop.
A drive fault coast-to-stop sequence displaying AU –– Auxiliary Interlock
–– which will cause the CR3 fault contacts to change state.
Important: A 5V DC or 5mA signal requires a gold contact relay.
