DCS800 Macros
The DCS800 includes macros that cover the most frequent parameter settings. Macros are pre-programmed parameter sub-sets. During start-up, the drive can be configured easily without the need to change many individual parameters by using a macro. The functions of inputs, outputs, and many allocations in the control structure are set up with the selection of a macro.
Twelve (12) macros are available, plus the factory default macro. The program also allows you to switch between macros with ease. Except for a few special cases, motor and tuning parameters will be maintained when switching from one macro to another.
The macro will define:
- whether the drive is speed-controlled or torque-controlled
- if two-wire (maintained) or three-wire (pulsed) motor-on inputs are being used
- if a DC contactor is being used
- the type of control that is needed (standard, constant speed, hand/motor-pot, etc.)
- the source of the command (digital and analog inputs and outputs or via high-speed-serial link)
- which actual values are available at the analog outputs
The selections include the following macros:
| Macro | Description |
| Factory | Resets all parameters to default values. |
| Standard | The Drive turns on with a maintained input. Motion is commanded with digital inputs (DI) RUN, JOG1, or JOG2. Run speed is set with an analog input. Jog speeds are set to preset levels. |
| Manual / Constant Speed |
Run speed is set with an analog input, but if one of two digital inputs is set, speed is changed to preset levels. Control is by way of 3-wire control (pulsed inputs). |
| Hand / Auto | A digital input switches between Hand (Local I/O) and Auto mode, and also switches speed reference. In Hand mode, speed is set with an analog input; in Auto mode, speed and motor control are set over a highspeed network, usually by a PLC. Manual control is 2-wire. |
| Hand / Motor Pot | A digital input switches speed reference from an analog input to Motor Pot. In Motor Pot mode, one digital input (MOTOR POT UP) increases speed and another (MOTOR POT DOWN) decreases speed. Control is 3-wire. |
| Motor Pot | Speed is always controlled through the MOTOR POT -UP and -DOWN digital inputs. Motor pot minimum speed can be released by setting a digital input to allow MOTOR POT DOWN to reduce speed to zero. Control is 2-wire. |
| Torque Control | A digital input switches between Speed and Torque control mode. While in Torque mode, an analog input is used as reference; while in Speed mode, speed is set to a preset level. A digital output can control a DC circuit breaker. Control is 2-wire. |
| Torque Limit | This macro is the same as “Standard,” except a second analog input determines torque limit. |
| 3-Wire Standard | Run speed is set with analog input, but if DI-1 is set, speed is changed to preset level. The drive turns on and runs with pulsed RUN digital input. It turns off with clearing of the STOP input. (3-wire control). |
| 2-Wire DC Contactor US |
This macro is the same as “Standard” except it also sets up the drive to control a DC contactor with a digital output. A DC contactor acknowledge input is required. |
| 3-Wire DC Contactor US |
This macro is the same as “3-Wire Standard” except it also sets up the drive to control a DC contactor with a digital output. A DC contactor acknowledge input is required. |
| User 1 and 2 | The user is allowed to record the current set of parameters as one of two “User Macros” and restore the drive to one of these sets. Restoration is done by setting or clearing a digital input or by sending a signal over a high-speed serial link. This is handy if, for example, the machine setup changes (i.e., making snow throwers half the season, and lawn mowers the other half) or if changing a drive from being a master to being a follower, etc. |
| 3-Wire Jog | For Flexpak3000 replacements. DI5 switches between Manual (AI1) and Auto (AI2) speed reference. Jog input (DI3) initiates motion and reverses with DI4. Control is 3-wire. |
